While the trigonometric functions may seem quite different from other functions you have worked with, they are in fact just like any other function. We can think of a trig function in terms of “input” and “output.” The input is always an angle. The output is a ratio of sides of a triangle.
WebSolution 1: As we saw above, \cos\theta=0 cosθ = 0 corresponds to points on the unit circle whose x x -coordinate is 0 0. Since these points occur at the points of intersection with the y y -axis, the possible values of \sin \theta sinθ are the possible y y -coordinates, which are 1 1 and -1 −1. _\square .
