In this tutorial the instructor discusses about the numeric coefficients that we come across while we work with polynomials. He goes on to discuss the numerical coefficient of a monomial stating that it is the number that is present before the variable in the monomial. He states that the numerical coefficient can also be negative or if there is no number present in front of the variable, it indicates that the numerical coefficient is one. This video helps in understanding what the numerical c...
This how-to video shows viewers how to solve math problems with brackets in polynomials. The person in the video teaches people how to solve the problem with a positive sign before the brackets. This segment does not show how to solve the trickier problem where there is a negative sign in front of the brackets. The tutor shows everything from removing the bracket due to the positive sign, to combining the similar terms for the result of the problem. This video can help anybody deal with brack...
To find a vertical asymptote, you are trying to find values of x that produce 0 in the denominator but not in the numerator. If 0/0 occurs, that means you have a "hole" in the graph. A vertical asymptote is a place in the graph of infinite discontinuity, where the graph spikes off to positive or negative infinity. To find the vertical asymptote, set the denominator equal to zero and solve for x. Check that the values also do not give a zero in the nominator. If the values work, you have found...
This video tells you how to find a slope of a parallel / perpendicular to it. In the equation y = mx + c, m is the slope. To calculate the slope of a line that is parallel to another line, you have to consider the rule m1 = m2 which means slope of the first line m1 is equal to the second line m2, if both the lines are parallel. Take the equation y = 2/3x - 7.2/3 is the slope. According to the rule m1 = 2/3 and so m2 = 2/3.Now to calculate the slope of perpendicular line you have another rule ...

In this tutorial the instructor shows how to write a Slope-intercept equation that is perpendicular to a line and passes through a point. He shows how to do this by solving an example with sample values. He says that the slope of a line perpendicular to the original line is the negative inverse of the slope of original line. Now he writes down the slope value in the general equation y = mx + c, and by substituting the sample value in the equation he obtains the value of the Y-intercept c, thu...
It’s just a few steps to make a toy motor. Take a battery of any brand, then take two safety pins. Attach them to both the sides of battery as they act as positive and negative. Then take a magnet, keep it on the battery. Now take a strip, which is rolled into a circle, and take two leading wires from it. Then keep this strip in between the safety pins and just start it up by rotating to one side. Then leave it aside, it rotates continuously.
This video teaches you a couple of tricks on installing crown molding, base boards, and casing. The tutorial advises the use of a negative rake blade to ensure a smooth cut. As always, you'll want to measure twice and cut once, but as far as your limbs go, don't cut those at all.
Like a lemon, a potato can produce electricity. This science experiment was prepared by Ebtisam Al Anzoor and demonstrated by Mustafa Daif. The electricity is proven using an analog micro ameter. The positive is copper from a penny or copper coin while the negative is a galavanized nail. The potato releases a charge and is further proven when it is connected to a calculator. You can daisy chain the potatoes for a greater charge.
Need an electric outlet and don't have one? No batteries on hand, either? Well, then you should use the next best thing - potatoes! In this tutorial, learn how to make that old science fair staple - the potato powered calculator! Check it out, it really works!
In general, the internet can be a cruel place, and Instagram is no exception. Most of the time, the platform is a fantastic way to share and view unique and creative content, to reach an audience of both fans and friends. People can step out of line and harass or bully others on posts to the detriment of the entire community. However, this type of commenting won't be sustainable for much longer.
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.
We all carry a bit of anxiety around with us. Is our boss still annoyed because we could barely stay awake in yesterday's pre-dawn meeting? Will our friend hate us forever because we forgot to call them back two weeks ago? Whatever worries pop up in your mind, whether they're monumental or insignificant, it can be hard to quiet those nagging voices, but you can shut down your nonstop mind with a bit of relaxation, distraction, and action.
Being the bearer of bad news is unpleasant; there's nothing more uncomfortable than offering up a spoonful of negativity. Whether you're a supervisor who spends a lot of time interviewing and rejecting candidates, or simply someone who has to say "no" to a friend, it's never fun to break bad news. But sharing unpleasant words or feedback with another person can become less of a burden with a few simple steps.
Volume markings on large pots and mixing bowls make life so much easier. They cut out the step of measuring and save you the trouble of washing measuring cups. However, there aren't many containers out there that actually have volume markers in them.
On Yay Math, Robert Ahdoot, founder of Yay Math, will show you some square root functions and some inequalities. He begins with the problem y=x². Then he makes a sketch with two intersecting lines in a t shape. The problem is illustrated by a curved U shape, the U's bottom resting on the horizontal bar, which represents x, while the center takes the vertical line. The vertical bar represents y. This U is directed up because the x² is a positive number. If the number were negative, the U would...

Jamie Smart from Salad Ltd demonstrating eye accessing cues and gestures. This is a great tool for helping people work out how they are dealing with certain issues. Is it an image, sound or feeling? Are they remembering something or constructing something? Once you've figured that part out you can move on to tackle the problem. For example is someone using internal dialogue for good or to beat themselves up? Are they constructing negative images that are holding them back? Taken from Salad's ...
Antibiotics are one of our main weapons against infections. The problem is that many bacteria are becoming resistant to most of the antibiotics we use to treat them, and those 'superbugs' have created an urgent threat to our global health. A research group found a new way to hit a well known bacterial target and have developed a drug to hit it.
The community of bacteria that lives in our gut has a lot to tell us. It can give clues to what we eat, the environment we live in, and diseases and disorders we may have. Now, scientists have linked these bacterial species to how we feel. A new research study found an association between women's gut bacteria and their emotions.
As sure as death and taxes, sitting at a wobbly table at one time or another is inescapable. With your weight on it, the table shifts from one end to the other, lifting one leg in the air and then the other; a parade of seesaws, especially if you have someone sitting on the other end.
Someone does't really like you. I don't know who or where they are, but they exist. If you want to change that, simply ask them to do you a favor.
One tweet can get your fired from your job. At least, in the cases of Gilbert Gottfried, Rashard Mendenhall, Ozzie Guillen, and Mike Bacsik, who were all either fired or forced to resign from their jobs after posting regrettable tweets online.
In the following video, I demonstrate how to create a device capable of charging the body of anyone who wears it with static electricity, allowing a powerful shock to be discharged into anything that is touched. This grants the wearer the ability to do some pretty amazing things, some of which are shown in the first segment of the video.
Rust protection doesn't have to cost a fortune. With a little zinc and some electricity, you can protect your precious metals from rust by galvanization. When you galvanize something, you're giving it a protective coating, and in this case, it's a zinc coating.
