Applications may include area, volume, work problems. The techniques we have developed thus far work very well for algebraic functions, but we are still unable to evaluate limits of very basic trigonometric functions. Recall that both sine and cosine are continuous functions and so the derivative is also a continuous function. 20 Using the Intermediate Value Theorem (1) Problem 21 Using the Intermediate Value Theorem (1) Problem We will also see the Intermediate Value Theorem in this section and how it can be used to determine if functions have solutions in a given interval. Whether or not two values are considered close is determined according to given absolute and relative tolerances.
