■ To use this Scientific Calculator/Complex Number Calculator enter any numeric expressions which can include complex numbers. This scientific calculator calculates and shows the results as you type. More ↓
■ You can use algebraic expressions, and expressions containing trig functions, exponential and logarithmic functions, hyperbolic functions with real or complex number arguments.
■ You can enter complex numbers in standard form, a + bi, or use the cis function to enter complex numbers in polar form, rcis(θ) which stands for r(cos(θ) + i sin(θ)) which is equal to reiθ.
■ If the result of a calculation is a complex number, it is automatically displayed in standard form and cis form (and its equivalent exponential form).
■ Warning: In Degree mode, you may get unexpected erroneous results if the argument of the non-algebraic functions you use in your expressions is not a purely real or purely imaginary number. Use Degrees with discretion when calculating complex number.less ↑ less ↑
