Basic Derivatives

* Let's use some formulas previously published. *

In mathematics, the derivative of a function is a measure of the speed with which changes the value of the mathematical function, as you change the value of the independent variable.

The derivative is the slope of the tangent line to the graph at point "X"

The easiest derivatives

If is a single number, no matter what, it always be 0

If is a number comes with a variable,  it always be the simple number without the variable.

If is a number comes with a variable and a exponent, you need to multiply the exponent times the number, and subtract 1 to the exponent.

It is exactly the same, only several times.

In this example, in order to don't get confused with the root, you can do what is shown.

In this you have to use the product rule. do the correct algebra.

In this you have to use the quotient rule (divisions), make the correct algebra.
