Everest, which straddles the border between China and Nepal, is the tallest mountain in the world. Measuring its height is no easy task. In fact, the actual measurement has been a source of controversy for hundreds of years. The measurement process involves the use of triangles and a branch of mathematics known as trigonometry. In this section, we will define a new group of functions known as trigonometric functions, and find out how they can be used to measure heights, such as those of the tallest mountains.

We have already encountered and evaluated integrals containing some expressions of this type, but many still remain inaccessible. The technique of trigonometric substitution comes in very handy when evaluating these integrals. This technique uses substitution to rewrite these integrals as trigonometric integrals. This integral cannot be evaluated using any of the techniques we have discussed so far. After substituting into the integral, we have. At this point, we can evaluate the integral using the techniques developed for integrating powers and products of trigonometric functions. After we evaluate the integral, we can convert the solution back to an expression involving x. The essential part of this discussion is summarized in the following problem-solving strategy.
