In this video we are going to take a look at derivatives of trigonometric functions. There are six basic trigonometric functions: sine, cosine, tangent, cotangent, secant and cosecant. So, first, we are going to introduce their derivatives. These derivatives should be memorized because we are going to use them a lot. There is a certain pattern for memorizing them. We are also going to see what sort of issues can arise, examine those issues, and discuss some ways to deal with them. Since many of these issues involve graphing, we will also draw a bunch of graphs.
memorize these formulas they are important!
The derivation of
the results for
is famous and involves a couple famous limits.
One type of
problem here simply incorporates trigonometric functions into
differentiation problems involving, for example, the Chain Rule.
You can use the
derivative formulas for
to derive the derivative formulas for the other trigonometric
