WebOct 23, 2024 · If we consider that the complex number 1 − i is graphed in Quadrant IV of the complex plane, and we recall how to use reference angles, we can see that the proper θ in this case is: θ = 2π − π 4 = 7π 4. Thus, the complex number 1 − i in trigonometric form is √2 ⋅ cis 7π 4, also written as √2(cos( 7π 4) +i ⋅ sin( 7π 4 ...
