Question from Christine, a student: I need help with this whole paper here is one problem csc^2x-cot^2x/1-sin^2x=sec^2x |
Hi Christine,
I would take
and write each of the trig functions in terms of sin(x) and cos(x). For example csc(x) = 1/sin(x). Simplify the left side using the fact that sin2(x) + cos2(x) = 1.
