identities: cosx/secx - cotx/tanx = cos^2x X tan^2x

[ca.chick]

cosx/secx - cotx/tanx = cos^2x X tan^2x

i know to combine the bases but im so confused what do i do to make both sides equal

Not true for x = \(\displaystyle \frac{\pi}{4}\\)

i know to combine the bases but...

I'm sorry but... what on earth do you mean by "combining the bases"? :shock:

Please pardon my confusion and reply with clarification. Thank you!

Eliz.

P.S. When you reply, please explain the relationship between the variables "x" and "X", if any. Thank you!
