Find the reciprocal of secant function given

The video tutorial explains how to determine the cosine function using the secant function. It begins by introducing the concept that secant is the reciprocal of cosine. The tutorial then delves into understanding reciprocal functions and how they apply to angles. Finally, it demonstrates how to find the cosine of an angle by taking the reciprocal of the secant value, using an example where secant is given as 5, leading to a cosine value of 1/5.
