How to use unit circle for inverse trig
WebSo the inverse trig functions are limited to producing certain possible outputs; i.e. sine always produces an angle in the right side of the unit circle, and cosine always produces an angle in the top half. So you can get cases where cos -1 (cos (x)) is not equal to x, because if x was like -pi/2, then the output of the function will be just pi/2.

Web20 sep. 2024 · A unit circle is defined as a circle whose radius is 1 unit, the centre is at the origin, and the circumference is 2π, since r = 1. Here, the arc length is equivalent to the measure of the central angle intercepting that arc. The trigonometric functions, sine and cosine have special importance in consideration for the unit circle. Web5 jan. 2024 · First to use a CALCULATOR to get the principle value as our base solution.
