Cos x = 0.789. Find sin x
Sample Answer
Certainly! You can find sin x using the unit circle and trigonometric relationships. Here’s how:
-
Unit Circle: The unit circle is a fundamental tool in trigonometry. It’s a circle centered at the origin (0,0) with a radius of 1. The cosine (cos) of an angle is represented by the x-coordinate of a point on the circle, and the sine (sin) is represented by the y-coordinate of that point.
