Polar form of complex numbers Complex number forms review Review the different ways in which we can represent complex numbers: rectangular, polar, and exponential forms. To find r, we must find the length of the line by using the Pythagorean theorem: To find , we can use the equation Note that this value is in radians, NOT degrees. solution: 10e^(i5.648) However that's wrong and I'm not sure why, the real answer is this: 10e^(-i0.650), 2.303 + i0.650, 2.303 - i0.650. Evaluate the trigonometric functions, and multiply using the distributive property.
