find the two values of theta in the interval 0 < theta < 360 degrees such that 4costheta = 1
------------------
cos(theta) = 1/4
Does that help?

4cos%28theta%29+=+1
cos%28theta%29+=+1%2F4
theta+=+2+pi%2An-cos%5E%28-1%29%281%2F4%29, n element Z
first find
cos%5E%28-1%29%281%2F4%29+=75.52° or 1.31811607 radians
that is
theta+=+2+pi%2An-cos%5E%28-1%29%281%2F4%29, if n+=0
theta+=+2+pi%2A0-cos%5E%28-1%29%281%2F4%29
theta+=1.31811607 radians
theta+=75.52°
second angle
theta+=+2pi%2A1-cos%5E%28-1%29%281%2F4%29, if n+=1
theta+=+2pi-1.31811607
theta+=+6.2831853-1.31811607
theta+=++4.96506923
theta+=284.295008°
