Hi. Looking for help on another trig proof. Here's the problem.
Prove that:
sec^6x (secx.tanx) - sec^4x (secx.tanx) =sec^5x.tan^3x
This one's got me baffled. Thanks in Advance,
Mike Clemmons

What have you tried?
Can I suggest taking outas a common factor first on the LHS
so
The rest should be easy...
