To solve cos(x) = 0, consider the unit circle. cos(x) = 0 when x = 90° and 270° To solve cos(x) - 1 = 0, add 1 to both sides then consider the unit circle. 2 0 1 2. U of S. I N T E G R A T I O N.

Thus we must have (e−y−ey. 2. )cosx = 0 and (e−y + ey) sin x = 1. If y = 0 the the first equality holds and the. Aug 5, 2022 ... Sin is the y coordinate of the intersection of the angle theta with the circle, and cosine is the x coordinate. So intrinsically to the circle, this equation ...
