Thanks for your help with the correction of my first attempt at the solution. I updated the page and hopefully it's better now.


I like how you use the Euler formula to illustrate the process of determining the system, however, I think a little more steps will make the final answer much easier to understand. - Bavorndej Chanyasak

________

I do not believe your proof is correct. You state that

$ e^{2jt} = \cos{t} + 2 j\sin{t} $

I think that is false.

$ e^{2jt} = \cos{2t} + j \sin{2 t} $

This problem can be proven using Euler's formula but I think you have incorrectly applied it.

Also I encourage you to learn LaTeX. It makes mathmatical expressions much easier to read - Chris Cadwallader
