Calculate as you type. If the result is a
complex number, this online complex number calculator gives the result in all different forms: a+bi, r∠(θ), re(iθ) and cos(θ)+isin(θ), using degrees or radians.
Use this online complex number calculator to calculate expressions containing complex numbers. You can enter complex numbers in the standard form a + bi or in polar form (phasor) r∠(θ) and get the result in all different forms. All algebraic functions, trig, exponential, logarithmic, hyperbolic functions with real or complex arguments are supported.
