Convert trigonometric form to complex numbers
WebMay 11, 2024 · When it comes to multiplying complex numbers, note this: $$\cos A + \cos B \ne \cos (A+B)$$ Instead: $$(\cos A+i\sin A)(\cos B+i\sin B)=\cos A \cos B-\sin A \sin B + i \sin A \cos B+ i\cos A \sin B)$$ $$=\cos (A+B)+i \sin (A+B)$$ Hence your overall result is correct, but your working is rather flawed.
