WebJan 2, 2024 · Exercise 5.2.1. Determine the polar form of the complex numbers w = 4 + 4√3i and z = 1 − i. Determine real numbers a and b so that a + bi = 3(cos(π 6) + isin(π 6)) Answer. There is an alternate representation that you will often see for the polar form of a complex number using a complex exponential. WebTo solve a trigonometric simplify the equation using trigonometric identities. Then, write the equation in a standard form, and isolate the variable using algebraic manipulation to solve for the variable. Use inverse trigonometric functions to find the solutions, and check for extraneous solutions.
