As you can see below, the cos-1 (1) is 270° or, in radian measure, 3Π/2 .

Amplitude: Find the Exact Value arccos(cos((3pi)/2)) Apply the reference angle by finding the angle with equivalent trig values in the first quadrant . The exact value of is . Note that the three identities above all involve squaring and the number 1.You can see the Pythagorean-Thereom relationship clearly if you consider the unit circle, where the angle is t, the "opposite" side is sin(t) = y, the "adjacent" side is cos(t) = x, and the hypotenuse is 1. The arccosine function is the inverse function of cos(x). arccos(x) = cos-1 (x) For example, If the cosine of 60° is 0.5: cos(60°) = 0.5. Then the arccos of 0.5 is 60°: arccos(0.5) = cos-1 (0.5) = 60° Arccos table where sin 2 θ means (sin θ) 2 and cos 2 θ means (cos θ) 2. This can be viewed as a version of the Pythagorean theorem , and follows from the equation x 2 + y 2 = 1 for the unit circle .
