Standard form, also referred to as standard index form is a method of writing really big and really small numbers. It uses powers of 10 to express its size.Standard form is used all the time in science an...

The key to long questions like these is picking out the key information quickly.
We have 2 pieces of information we are interested in, the number of shots and the radius of each shot, so let's assign...

Suppose you have an equation: (2x+3)/(x-4) - (2x-8)/(2x+1) = 1 and you want to solve for x.

Remember that you can only add fractions if they share a common denominator. Also that you can ...

Suppose you have 2 functions: f(x) = 3x², g(x) = log₃(x). These are arbitrary, any functions would work. Evaluate f(g(x)): let y = log₃(x) ( = g(x) ), then f(g(x)) = f(...

The most important thing to remember when differentiating implicitly is that y is a function of x. Rewriting y as y(x) often makes it much clearer. For example, evaluate d/dx (y²): using the...
