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. WebWe just saw how to find an angle when we know three sides. It took quite a few steps, so it is easier to use the "direct" formula (which is just a rearrangement of the c 2 = a 2 + b 2 − 2ab cos(C) formula). It can be in either of these forms: cos(C) = a 2 + b 2 − c 2 2ab. cos(A) = b 2 + c 2 − a 2 2bc. cos(B) = c 2 + a 2 − b 2 2ca bonsfm ファイラー
