WebSo if you start at 0 degrees, you are to the right, so cosine is one and sine is zero. If you increase the angle, the cosine will start decreasing slowly (as you are moving slowly leftward) while the sine is increasing (as you move up). You reach the top at 90 degrees. Since the circle is symmetric, increasing. 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.
