"WebSep 29, 2024 · Add a comment. 2. was how we get e − i θ = cos θ − i sin θ from e i ( − θ) = cos ( − θ) + i sin ( − θ). The answer is that cos ( − θ) = cos ( θ) and sin ( − θ) = − sin ( θ) (cosine is an even function, and sine is an odd function). Share. Cite. Follow. answered Sep 29, 2024 at 1:36. " - Cos theta sin
