This video teaches us the method to find the circumference of a circle given its radius. The video tells us to find the answer in terms of pi and also to the decimals value. The formula to find the circumference is two times the product of pi and the radius. The first step involves the drawing the circle and marking the radius. The radius of the circle in the video is 6.5 cm. Now use the formula to find the circumference. Substitute the value of the radius in the formula of circumference. We ...
Learn how to easily convert percentage values into decimals in this quick video. When converting percentages it is important to remember that a percentage simply means to divide by 100. For example, take 5%. That means 5 divided by 100 or 0.05. These can easily be done on your calculator once you understand the meaning of percentage. Another example, let's take 23%. Divide 23 by 100 and you get .23. Finally, as a last example takes 99%. Take 99 divide it by 100 and the answer will come out to...

The indeterminate doesn’t really show up in everyday living, but in ...
This video teaches how to convert a value in Celsius to Fahrenheit in simple steps. First take a paper and marker and keep in mind a Celsius value (e.g-32) to convert into Fahrenheit.

Now round it off the and your final result will be 90 degree Fahrenheit.
To find the slope of a line you must have two points and then you must plug in the two points into the slope formula. The slope formula is m= y2-y1 over x2-x1. If the slope is a fraction be sure to reduce to the lowest. Remember if a number is divided into zero it is zero, if zero is divided into the number it is undefined. A calculator can help one remember this. Horizontal lines have slopes and vertical lines do not. Drawing the lines on a graph can help you see the actual slopes and which ...

The video is a tutorial in trigonometry. The teacher teaches that the tangent or the tan of an angle is the ratio of the opposite side to the adjacent side of a right angled triangle. If one side and one angle is given then the value of the unknown side can be found by solving the equation tan of angle is equal to opposite upon adjacent side. If the angle is to be found then the tan inverse of the value is seen in the calculator.
In this video tutorial the author shows how to use the Cosine Law. He shows how to find an angle of a triangle where he know all the sides of a triangle, using the cosine Law. He uses a lower case letter to designate a side and a capital letter to designate an angel apposite to that side. He gives the formula for the cosine law using a triangle as an example. Now he goes on and demonstrates how to use a scientific calculate. He shows how to use the degree mode in the calculator to solve these...
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.

More and more devices are using iOS 8 over iOS 7, and that means more and more developers are adding iOS 8-friendly features to their apps, especially widgets. However, not every widget available for your Notification Center right now is awesome. Take for example the Dropbox widget—it's essentially nothing more than a real-time notification, as the only action it performs is opening a recently updated file within the app.

Apple doesn't include its Calculator app on the iPad and never did. One almost appeared over 12 years ago but was nothing more than a blown-up version of the iPhone app. Since then, the company still hasn't made an iPad-optimized calculator, and there is no shortage of third-party alternatives to fill the gap. It may happen one day, but for now, these are the best calculator apps for your iPad.
