Synopsis
template<typename T>
complex<T> polar(const T& r, const T& theta)The polar function returns
a complex object that represents the value given in polar
coordinates, in which r is the
magnitude and theta is the angle
(in radians). The resulting value has the following real and
imaginary parts:
real = r * cos(theta) imag = r * sin(theta)
