- Simplify the following expression using euler's formula. (The problems in the pic)
- e^i Θ = cos Θ+isin Θ
The following is the questions given. I solved the first one, which steps are shown below.
But I am not sure if this is how the question wants me to solve the problem. Would you tell me if the way I solved the problem is the proper way of simplifying the expression using euler's formula?
Also, I did try problem b, but I am not sure how to proceed or where to use the euler's formula.
Thank you for your help!
