If ω is a non-real cube root of unity, then what is a root of the following equation?
x = ω
In this case, x = ω is a root of the equation because ω is the cube root of unity.
If A + iB = tan (x + iy), then the value of tan 2x is?
The value of \({\left( {\frac{{\cos \theta + i\sin \theta }}{{i\cos \theta + \sin \theta }}} \right)^4}\) is:
