SymPy Gamma

SymPy:

im (symbols ("x",imaginary =T))

$- i x$

Abs(-I*x)

$\left|{- i x}\right| =$

atan2(*(-I*x).as_real_imag()).evalf()

$\operatorname{atan_{2}}{\left(- i x,0 \right)} =$

conjugate(-I*x)

$- i x =$

Plot:

Roots:

solve(-I*x, x)

$x =$

diff(-I*x, x)

$\frac{d}{d x} \left(- i x\right) =$

series(-I*x, x, 0, 10)
