This free imaginary number calculator will simplify any complex expression with step-by-step calculations quickly. example. The real part is 2 and the imaginary part is 3, so the complex coordinate is (2, 3) where 2 is on the real (or horizontal) axis and 3 is on the imaginary (or vertical) axis. This is what is going on with our power. If the phase angle was 90, the projection on the real axis would be zero, and the imaginary part would be equal to the magnitude. The Complex Number Calculator solves complex equations and gives real and imaginary solutions. You also have the option to opt-out of these cookies. However, the naive tan 1 definition does obscure the fact that a complex number with negative real part and negative imaginary part lies in the 3rd quadrant: the range of t a n 1 is [ 2, + 2] which is only radians or 180 degrees wide - it covers only half of the phase space. However, there's no real number that gives the square root of a negative number. amazing app, i know you might think it is just to cheat with but it actually shows you the answers, and even sometimes graphs with steps to how it got there.
