An imaginary number is the square root of a negative number. We can always come back from polar to algebraic notation. However, an online Scientific Notation Calculator allows you to add, subtract, multiply, and divide numbers in scientific notation. This should be geometrically obvious as well: the Real Line is a subset of the Complex Plane. To multiply complex numbers the imaginary number calculator use formula as: F * G = | z_1| * exp (i_1) * | z^2| * exp (i^2) = | z_1 * z^2| * exp (i(_1 + ^2)), we see: A * B = | z_1 * z^2| and arg (A * B) = _1 +^2. Calculator | First, the imaginary numbers calculator finds a general formula for the complex power of two numbers, given as A * B. AB = (x + yi) (m + ni) = Since it is not clear how to extend this expression, the complex calculator use F as the polar form of a complex number. In this case the current lags the voltage by 90, but the average power is also zero. Finally, the opposite side of the triangle corresponds to the imaginary axis and is the Reactive Power (Q) given by Q = V I sin , measured in Volt-Amps Reactive (VAR). Complex Number extends the concept of one-dimensional line to a two-dimensional complex plane and uses the horizontal axis for the real part .
