Formula for complex power
WebFor even powers, you can first square the complex number, and then take that result to half the original power which can be quick depending on the complex number and the … WebEuler's formula eiφ = cos φ + i sin φ illustrated in the complex plane. Interpretation of the formula [ edit] This formula can be interpreted as saying that the function eiφ is a unit complex number, i.e., it traces out the unit circle in the complex plane as φ ranges through the real numbers.
