How do you find the integral of # cos^4 (x) dx

Web1 Answer. Sorted by: 1. Aloha Curious, This formula is the law of cosines for spherical triangles. If you stick three dots on a sphere, and connect the three dots with the shortest segments you can, you get a spherical triangle. The interior angles α, β, and γ are similar to the angles in a flat triangle; they're just the angles between the ... WebBecause the x- and y -values are the same, the sine and cosine values will also be equal. Figure 9 At t = π 4 t = π 4 , which is 45 degrees, the radius of the unit circle bisects the first quadrantal angle. This means the radius lies along the line y =x y = x. A unit circle has a radius equal to 1. WebApproximating cos(x) with a Maclaurin series (which is like a Taylor polynomial centered at x=0 with infinitely many terms). ...
