10 сент. 2022 г. · Use a compass, protractor, and a ruler. If you want sin -1 (0.8), you use the compass to draw a circle of radius 1. Measure a height of 0.8 on the y-axis.

To find the exact value of trig functions without a unit circle, we need to check the quadrant in which the angle falls. Let us proceed step by step.

17 нояб. 2022 г. · We tend to denote an inverse trig function with an “exponent” of “-1”. In other words, the inverse cosine is denoted as cos−1(x) cos − 1 ( x ).

13 мая 2013 г. · The way to go about this is to express all known trig functions in terms of sin x and cos x and then solve for sin x and cos x.
