WebUnit Circle. 30°. Click the card to flip 👆. π/6. Click the card to flip 👆. 1 / 103. WebThe answer is 135°. With inverse cotangent, we select the angle on the top half of the unit circle. Thus cot -1 (–1) = 135° or cot -1 (–1) = 3π/4. In other words, the range of cot -1 is defined to be the angles on the upper half of the unit circle as pictured below. The range of cot -1 is restricted to (0, 180°) or (0, π).
