Complex Number Calculator

This scientific calculator / complex number calculator is for calculating mathematical expressions containing real, imaginary and, in general, complex numbers.

Developed as a fully functional scientific calculator, it accepts expressions involving mixtures of complex numbers in standard (rectangular) a+bi and polar (phasor) r∠(θ) forms such as

(1/2 + 2i)(3 + 4i) + 3∠(π/4) + sin(i)cos(2 + 3i)^(4 - 2i) / ln(2+i)

You can use all standard mathematical functions & operations:

• addition, subtraction, multiplication, division
• exponentiation
• parallel sum, || (used in electrical engineering, for example)
• power, exponential & logarithmic functions
• trigonometric functions and their Inverses
• hyperbolic functions and their Inverses
• Gamma function, Γ
• Psi function, Ψ
• Zeta function, ζ

With it's unique and intuitive user interface, this scientific/complex number calculator displays the result of complex number calculations in standard form and optionally converts it to polar and other modular forms.

(Long press i or ∠ to see all forms of the calculated result).

Scientific/complex number calculations can be performed in RAD (radians) or DEG (degrees) mode.

The results can be displayed with fixed, scientific and engineering notations.

Other Features

• As a scientific calculator, you can use it to enter a function f(x) or parametric equation p(t) and generate table of values.

Do statistics with one or two dimensional real data (you can also use expressions of complex numbers for data as long as they evaluate to real numbers):
• x1, x2, …
• x1, y1; x2, y2; …
Press Σ to do the calculations.

• Calculate combinations C(n, r) and permutations P(n, r).

• Scientific constants.
• Unit converter (Mass, Length, Velocity, ...)

This complex number calculator comes with a built-in instructions.
