asked $\cot(x)$ or $\tan(x)$ amplitude with $F(x)$ or $G(x)$?

Yes I'm definitely going to go through it ASAP as it makes it much easier to read.. It's just due to time today.

comment Trigonometric Identity - $\tan(\pi/2 -x) - \cot(3\pi/2 -x) + \tan(2\pi-x) - \cot(\pi-x) …$
Yes I was able to solve it very easily with the knowledge of sec^2x -tan^2x = 1 . Thank You.

Ok makes sense... Is sec^2(x) - tan^2(x) = 1 created off of sin^2x + cos^2x = 1 because we haven't learned that and this is a Grade 12 course.

comment - Trigonometry Identities - If $2\sin(x-y) = \sin(x+y)$, find $\frac{\tan(x)}{\tan(y)}$
Therefore, sin(x+y)/sin(x-y) ?

Ok, I see what you did... should I bring the right side over to the left side OR simplify each side if possible?

You're all hilarious... However it's actually a homework question that is likely on the my test tomorrow worth 30% of the mark. I'll edit to show some steps.
