(2  sinx)/cosx = cot x = cosx/sinx
Multiply both sides by sinx cosx
2 sinx  sin^2x = cos^2 x = 1  sin^2x
2 sinx = 1
x = 30 degrees or 150 degrees

I'm trying to verify these trigonometric identities. 1. 1 / [sec(x) * tan(x)] = csc(x)  sin(x) 2. csc(x)  sin(x) = cos(x) * cot(x) 3. 1/tan(x) + 1/cot(x) = tan(x) + cot(x) 4. csc(x)/sec(x) = cot(x)
