The cosine function is negative in the second and third quadrants. x = arccos(−1) x = arccos ( - 1) Simplify the right side. Take the inverse cosine of both sides of the equation to extract x x from inside the cosine. Use the form to find the variables used to find the amplitude, period, phase shift, and vertical shift. To find this answer on the unit circle, we start by finding the sin and cos values as the y-coordinate and x-coordinate, respectively: sin 30° = 1/2 and cos 30° = √3/2.
