For math, science, nutrition, history 2019-11-14 sin(x) = 0 or cos(x) = 1/2 So our solutions are all the angles whose sin is 0 or all the angles whose cos is 1/2. Since "x" was used for the angle instead of theta, I'm assuming we want radian measure angles. (If you need angles in degrees, just replace all the 's in the answers we get with 180 and simplify.)

The trick is to rewrite the $\cos^2(x)$ in the second step as $1-\sin^2(x)$. 2018-10-29 · Cos^2x-sin^2x = cos 2x. so cos 2x = 0. so 2x = pi/2 or 3pi/2 . 2x = 2npi + pi/2 and 2npi + 3pi/2. x = npi + pi/4 and npi + 3pi/4 ,,,,, where n is integer.

In my calculus class, my teacher is using sin^2x I never saw anything like that.. Is it the same as (sinx)^2? Thanks
