Is there a reason you're unsure?Answer:
tan 3465 degree = tan 45 = 1
right?
When is tan(x)=1 on the unit circle?somehow
Are you saying you just guessed??somehow
tan(Θ) = tan(Θ ± n * π)Answer:
tan 3465 degree = tan 45 = 1
right?

Why mod 360 and not 180?
The solutions exist in the first and third quadrant of the unit circle. Mod 360 only provide the solution in the first quadrant, either/or third, but not both.either / or
Yeah sure but 3465 (mod 360) = 225 and it's only one more step to say that \(\displaystyle tan 225\degree = tan 45\degree\).The solutions exist in the first and third quadrant of the unit circle. Mod 360 only provide the solution in the first quadrant, either/or third, but not both.
The OP's goal was to show tan(3645)=tan(45).
3465 mod 180 = 45
It's because sin(x) and cos(x) have a period of [imath]2\pi = 360 \degree[/imath] and tan(x) has a period of [imath]\pi = 180\degree ?[/imath]mod 360 will lead to the answer for sin and cos as well, mod 180 won't.
Yes, but my point was you can use mod 360 in all cases, but mod 180 only for tan. Trying to keep it simple.It's because sin(x) and cos(x) have a period of [imath]2\pi = 360 \degree[/imath] and tan(x) has a period of [imath]\pi = 180\degree ?[/imath]
