- abs_arg(c, deg=False)
- conversion of complex number: real, imag -> absolute value, polar angle
- arg(c, deg=False)
- conversion of complex number: real, imag -> polar angle
- atan2(...)
- atan2(y, x)
Return the arc tangent (measured in radians) of y/x.
Unlike atan(y/x), the signs of both x and y are considered.
- cos(...)
- cos(x)
Return the cosine of x (measured in radians).
- norm(c)
- polar(a_t, deg=False)
- conversion of complex number: polar representation -> real, imag
- sin(...)
- sin(x)
Return the sine of x (measured in radians).
