Taking this formula 9x²+y²=9 your instructor shows you how to find the solution for the variable y. Finding a second derivative is no more difficult that finding the first derivative, you only have to do the problem equation through twice. The derivative of 9x² will be 18, of y² will be 2y [this is the same as 2(y), 2 x y or 2 * y]. The problem now goes -18x + 2y dy/dx=0. This equation is solved for dy/dx making the next step in the problem go -18x 18x+2y dy/dx=0-18x, 2y dy/dx= -18x. The next...

Learn how to replace the factor airbox with a cone filter intake - this should flow more air through your engine to add a bit of horsepower and better performance.
When it comes to cybersecurity, one layer isn't enough. A complex password (or one created with a password manager) does a good job of protecting your data, but it can still be cracked. Two-factor authentication strengthens this by adding a second layer of security, giving you even more protection against online threats.
The Pixel 4 isn't for everyone, but it does have its appeal in several specific use cases. Thanks to Instagram, YouTube, and other social media platforms, the fitness industry and smartphone world are now intertwined like never before, and it appears Google's aware of this.
Let's be honest, nobody enjoys doing cardio — they tolerate it. That dreadful, loathsome feeling you experience when you're doing cardio workouts isn't unique to you, it's almost universal. Sure, it gets easier the more you do it, but there are some ways to make it better now.
Many online users worry about their accounts being breached by some master hacker, but the more likely scenario is falling victim to a bot written to use leaked passwords in data breaches from companies like LinkedIn, MySpace, and Tumblr. For instance, a tool called H8mail can search through over 1 billion leaked credentials to discover passwords that might still be in use today.
They're finally here. Apple announced three new iPhone models at their "Gather Round" event in Cupertino, and they're all absolutely gorgeous phones. With bezel-less screens and polished titanium edges, the iPhone XS, XS Max, and XR are truly marvels of engineering — but perhaps the most impressive design feat Apple pulled off is the fact that two of these models are rated IP68 under the IEC standard 60529.
Another piece of Magic Leap's mysterious story has been uncovered thanks to a new patent application revealed on Thursday, March 15.
On average, an office worker receives 121 emails a day. Many of these emails are trivial and don't require immediate attention. While Gmail's automatic spam filters catch plenty of irrelevant emails, some still make their way into your inbox. Fortunately, Gmail's tools aren't limited to just spam filters.
Most of us have never put much thought into this, but the question needs to be asked — what exactly happens to all of our online accounts when we die? No, the internet won't just know and delete accounts for you, so you need to plan for life's one guarantee. Because without a plan, things become a lot harder to sort out.
It finally happened! In a world of "go big or go home," Magic Leap has finally done something other than tease us with vague promises and rendered video concepts. Although, other than actually showing us what the developer's kit will look like, it seems little more than a slightly different kind of a tease. To demystify this new product, we here at Next Reality decided to put together what we know about the hardware.
When it comes to security, Apple is usually at the top of the pack when it comes to your personal data, minus a few embarrassing flaws here and there. However, a new iOS security concern has been discovered that protects your data less than it did before — and Apple designed it like that.
In case you didn't catch the big event in Cupertino, Apple just unveiled two of the most cutting-edge phones ever made — the iPhone 8 and the iPhone X. Out of the many glorious specs that were rattled off on stage, one stands out for being just a little confusing: Both models are rated IP67 under the IEC standard 60529.
The large, dome-shaped LiDARs that have become a fixture on driverless car prototypes are expensive and notably ugly. And yet, these unsightly devices should remain planted on driverless cars, even when they become available in commercial fleet services across the country in a couple of years.
How can a drug used to treat cancer be effective against viruses, too? The answer lies in the drug's shared target — specifically, cellular components that control the activity of genes. A new research study showed that one such type of drug, histone methyltransferase inhibitors used in cancer clinical trials, has activity against herpes simplex virus, too.
During the millions of years they've been on earth horseshoe crabs have developed a trick that can save our lives even now — and may be especially useful in the fight against healthcare-associated infections.
Sex makes the world go 'round, and when it does, so does gonorrhea. Finally some good news on the growing menace of drug-resistant gonorrhea — a large, long-term study shows a vaccine may work in reducing the incidence of an increasingly dangerous infection.
Killing more than 29,000 people each year, infection with Clostridium difficile (C. diff or CDI) is the most common healthcare-associated infection in the US. In a disturbing development, new research reveals recurring cases of the infection are soaring.
That soil under your feet is not just dirt. It is teeming with life that may not change as fast as we would like when challenged by global warming.
Intense exercise can cause problems with our digestive tract. It even has a name — "Exercise-induced Gastrointestinal Syndrome." Simply put, strenuous exercise can damage the gut and let the bacteria that reside there potentially pass into the bloodstream.
The future of forests looks dreary in the face of a warming climate, but scientists are exploring the relationship between soil microbes and the ability of trees to move to higher altitudes, a key component of their survival.
Are you looking for a little microbe magic? Think composting. Composting is a great way to reuse food and plant waste that you would otherwise throw into the trash, which would just end up in a landfill somewhere. During the composting cycle, microbes reduce this organic waste until it can be fed back into the soil as rich, crumbly compost. When returned to the soil, compost feeds plants and improves the nature of life underground. Sound like a great idea? It is — and it's easy.
I had the opportunity to speak with the COO of Osterhout Design Group, Pete Jameson, shortly before the announcement of the company's R-8 and R-9 smartglasses models at CES in January. And while I sadly could not make it to CES to test the smart specs out right away, ODG invited me to do just that while I was in San Francisco for the Game Developers Conference.
Even if your cat drives you a little nuts, don't worry, because a new study says that cats pose no risk to your mental health.
Japan is in the process of curbing its aging population and mature workforce. According to The Diplomat, the country's population has been declining at a steady rate. To meet future productivity demands in commercial and industrial sectors, local officials are turning to self-driving technology, including truck platooning, where three or five vehicles travel autonomously in a string formation. This practice, according to a study by MIT, can reduce fuel consumption by up to 20% (more about thi...
In the summer of 1976, 4,000 American Legionnaires descended upon the Bellevue-Stratford Hotel in Philadelphia, Pennsylvania, for a four-day convention. Several days later, many of the attendees experienced symptoms of severe pneumonia. By the beginning of August, 22 people had died. The Centers for Disease Control and Prevention (CDC) estimate that about 180 people were sickened and 29 people died before this mysterious outbreak burnt out.
A young child becomes very thirsty very often and seems tired all the time. A visit to the pediatrician determines she has type 1 diabetes. The onset of type 1 diabetes may seem sudden, and it can be, but the disease may actually have been triggered by common childhood viruses years earlier.
Using mathematical modeling, researchers suggest weather and warming created the "perfect storm" that drove the Zika outbreak in 2016.
Starting in October, many Nexus 6P users have been experiencing a bug that causes their phone to completely shut down, even though there was 20% or more battery life remaining. At first, it was thought to be a direct result of the recent Android Nougat update, but a combination of factors indicate that this isn't necessarily the case—or, at least, it's not the only problem.
With the height of the flu season ahead, there are some good reasons to keep a flu vaccination in mind.
Google's new Project Fi cellular carrier has been making waves across the mobile industry, so we decided to put it to the test against T-Mobile, one of the more established networks. For the actual testing, we slapped a SIM card from each carrier into two identical Pixel XL phones, which offer full compatibility with both networks.
Plastic wrap is, arguably, man's greatest invention—or at least, the 2000 Year Old Man thought so. Its primary use is to protect food from getting dried out in the fridge or on the counter; but if that's all you're only using it for, you're missing out.
We like our Egg McMuffins around here, albeit homemade with our preferred ingredients: whole wheat (or homemade sourdough) English muffins, a slice of thick Tillamook cheddar cheese, a meat, perhaps, like Canadian bacon, and finally—that perfectly-fried, perfectly-shaped egg.
