I'm trying to understand why 2cos2x would equal 2, when x=0.
So that would make it 2cos2(0), which should make the whole thing 0 (zero)? At least I thought so?
I'm trying to figure out how to use the two sin/cos/tan triangles in calculus of:
1) ?(2), 1, and 1
and
2) 2, ?(3), and 1
If anyone knows exactly what i'm talking about at all....can't really draw on here....thanks!
