I can't seem to remember how to find the amplitude/phase of a complex function (I do know what to do for complex numbers, though). I know it's in my mind somewhere, but I just can't remember lol. So, for example, how would I find the amplitude/phase of:

3+j5t

and

3ej4t

EDIT: I know for 3ej4t, the amplitude is 3.

Thanks

Those are complex numbers, so where is the issue? I don't even see a function in your post.
t is a variable, so what - just treat it as an unknown number (probably real, especially if t is time).
