I need to reduce trig identities to the simplest form. i was wondering if you could take me further.
(secx)(cscx)-tanx

cotx(1/secx)+sinx
i changed the top to (1/cosx)(1/sinx)-(sinx/cosx)
Thats as far as i can do it

Let's concentrate piece by piece.
1.
First off, you should immediately recognize the identity found in the denominator. As for the numerator, if you know your sin
and cos graphs like the back of your hand:
which is just y = cos x shifted to the right by pi/2. What would that be?
2.
3.
Ignoring the negative sign for now, if you shift the graph y = tanx to the left by pi, what do you get?
4.
Im not trying to be mean but unless i see steps it cant help me.
By the way this isnt really for a grade, but she said these will be on the tests. So id really like to study and memorize the rules with them. I need to see the whole thing. Ill try to look over it again
