9(sex^2 (x)) - 5(tan^2 (x)) = 5 + 4(sec^2 (x))

ALSO:

What does it mean when a number (in the case above we have 9, -5 and 4) is written IN FRONT of trig identities?

Establish the identity

csc^4 (x) - csc^2 (x) = cot^4 (x) + cot^2 (x)

ALSO:

I need someone to carefully and easily explain how to break down trig identities with powers greater than 2.

For example, above we csc^4 (x) and cot^4 (x). How do I play with trig identities whose power is greater than 2?
