The returned value is in the range [-Pi, Pi]. func Polar(x complex128) (r, θ float64) Polar returns the absolute value r and phase θ of x, such that x = r * e**θi. The phase is in the range [-Pi, Pi]. func Pow(x, y complex128) complex128 Pow returns x**y, the base-x exponential of y. For generalized compatibility with math.Pow: Pow(0, ±0) returns 1+0i Pow(0, c) for real(c)<0 returns Inf+0i if imag(c) is zero, otherwise Inf+Inf i. func Rect(r, θ float64) complex128 Rect returns the complex number x with polar coordinates r, θ. func Sin(x complex128) complex128 Sin returns the sine of x. func Sinh(x complex128) complex128 Sinh returns the hyperbolic sine of x. func Sqrt(x complex128) complex128 Sqrt returns the square root of x. The result r is chosen so that real(r) ≥ 0 and imag(r) has the same sign as imag(x). func Tan(x complex128) complex128 Tan returns the tangent of x. func Tanh(x complex128) complex128 Tanh returns the hyperbolic tangent of x.
