Formulas for tangent of complex number


In the following description, \(z\) stands for the complex number. \(x\) stands for the real value \(Re\) and \(y\) for the imaginary value \(Im\).

\(\displaystyle tan(z) = \frac{sin(2x)}{cos(2x)+cosh(2y)} + \frac{sinh(2y)}{cos(2x)+cosh(2y)}i\)

Example

\(tan(z) = sinh(0.3+0.5i)\)
\(\displaystyle tan(z) = \frac{sin(2\cdot0.3)}{cos(2\cdot0.3)+cosh(2\cdot 0.5)} + \frac{sinh(2\cdot0.5)}{cos(2\cdot0.3)+cosh(2\cdot 0.5)}i\)
\(\displaystyle tan(z) = \frac{sin(0.6)}{cos(0.6)+cosh(1)} + \frac{sinh(1)}{cos(0.6)+cosh(1)}i\)
\(\displaystyle tan(z) = \frac{0.565}{2.368} + \frac{1.175}{2.368}i\)
\(\displaystyle tan(z) = tan(0.3+0.5i) = 0.238+0.496i\)
