Derivatives of Trig Functions

In this section we will see derivatives of functions other than polynomials or roots of polynomials. We'll begin this process off through taking a look at the derivatives of the six trig functions. Two derivatives will be derived. The remaining four follow similar proofs for the two given here.

Before we in fact get into the derivatives of the trig functions we need to give a couple of limits which will show up in the derivation of two of the derivatives.

Fact

Before we begin differentiating trig functions let's work a quick set of limit problems that this fact now allows us to do.
