High School Math Solutions – Derivative Calculator, Trigonometric Functions

In the previous posts we covered the basic algebraic derivative rules (click here to see previous post). But how can we derive trigonometric functions?  Simply by memorizing some common trig derivatives:

(sin(x))’ = cos(x)

(cos(x))’=-sin(x)

(tan(x))’=sec²(x)


Let’s start with an example, (click here):
