Do you need help or do you want us to do your students work? 🙂
Anyway, here are a few ways - I usually prefer to do the work in the complex plane as it makes a lot of things quite easy.
Guess you mean L13 or L23 in your functions. not L12.
Easiest way seems to be an interpretation as complex numbers.
Thanks, Werner!
