Exercise 5.E. 3. For each of the following pairs of complex numbers w and z, determine the sum w + z and illustrate the sum with a diagram. WebOct 2, 2014 · An easy way to find any trigonometric for is by using complex numbers norms and the equation sin²(θ) + cos²(θ) = 1. Choosing a generic complex a +bi, we find its trigonometric form by dividing a for the numbers norm ( √a² +b²) which will result in the cosine of the θ angle that the number refers to. a + bi = (√a² +b²) ⋅ cis(arccos( a √a²+ b²)) ∴ WebTrigonometric form can be used to multiply, divide, and find roots of complex num-bers more easily than is the case with rectangular form.
