# Complex Numbers Calculator

## Settings

Number of digits:

With the online calculator for complex numbers can be calculated basic arithmetic and many other values such as amount, square, polar representation, .... The corresponding input of real and imaginary parts of the complex number in the text boxes complete with return and the values will be computed.

## Values of elementary functions f(z)

$z=x+i\phantom{\rule{0.3em}{0ex}}y$

= $+\phantom{\rule{0.3em}{0ex}}i$

## Calculator for addition / subtraction of complex numbers

${z}_{1}={x}_{1}+i\phantom{\rule{0.3em}{0ex}}{y}_{1}$

= $+\phantom{\rule{0.3em}{0ex}}i$

${z}_{2}={x}_{2}+i\phantom{\rule{0.3em}{0ex}}{y}_{2}$

= $+\phantom{\rule{0.3em}{0ex}}i$

## Calculator for the multiplication of complex numbers

${z}_{1}={x}_{1}+i\phantom{\rule{0.3em}{0ex}}{y}_{1}$

= $+\phantom{\rule{0.3em}{0ex}}i$

${z}_{2}={x}_{2}+i\phantom{\rule{0.3em}{0ex}}{y}_{2}$

= $+\phantom{\rule{0.3em}{0ex}}i$

## Calculator for the division of complex numbers

${z}_{1}={x}_{1}+i\phantom{\rule{0.3em}{0ex}}{y}_{1}$

= $+\phantom{\rule{0.3em}{0ex}}i$

${z}_{2}={x}_{2}+i\phantom{\rule{0.3em}{0ex}}{y}_{2}$

= $+\phantom{\rule{0.3em}{0ex}}i$

## Polar to Cartesian conversion

$z=r\left(\mathrm{cos}\phi +i\mathrm{sin}\phi \right)$

$\phantom{\rule{1.3em}{0ex}}r\phantom{\rule{0.3em}{0ex}}=$ $\phantom{\rule{1.3em}{0ex}}\phi \phantom{\rule{0.3em}{0ex}}=$
