WebPerhaps that is why Euler's formula works! And when you look into it actually does explain why it works because since both the derivatives of trig functions and powers of i have a "cycle" of 4, only the powers of x and the factorials don't cycle, which is exactly like the Maclaurin expansion of trig functions so you can factor out the cos(x) and i*sin(x) to get … WebSine power-reduction formula: an illustrative diagram. The shaded blue and green triangles, and the red-outlined triangle E B D {\displaystyle EBD} are all right-angled and similar, and all contain the angle θ {\displaystyle \theta } . WebThe given equation is e e − i θ. Step2: Formula Used According to Euler, e ± i θ = cos θ ± i sin θ. For convenience e − i θ = cos θ − i sin θ can be written as z = r e - i θ - - - - 1 Where r is amplitude. Step3: Simplify the given expression z = e e − i θ z = e cos θ − i sin θ z = e cos θ ⋅ e − i sin θ − − − − ( 2) shelly from celebrity rehab
