cos x = sin 2x on [0;2pi]

This was on my mock exam and my mind just imploded. I hate sines...

I don't quite understand the format you've put that in. Maybe format it better or get a screenshot of the paper?

Sines are awesome. Whenever you have a gay-ass SOH-CAH-TOA question, you can simplify it and save so much fucking time by using the sine rule. But that's going off on a tangent to your question.

Spoiler:

See what I did there?
