Need a trig explanation?
I tried posting this question last night, but I got a sole response that didn't help. Better luck during daytime?
I came across questions that might be asked on my Trig Final that I have no idea how to do. If you could tell me how to do these? An example problem:
Given that cos x + i sin y = sin x + i, find all correct x and y values between 0 and 2pi.
Wow, that made it click. Seems so much simpler than what I was trying to make of it xD

equate the real parts
equate the imaginary parts
cos x = sin x
x = π/4, 5π/4
i sin y = i
sin y = 1
y = π/2, 3π/2
