Question

Proving identities...fun!

Verify the identity.
Cosx/(secxsinx)=cscx-sinx

Answer 1

It's all about knowing your ratios, list all your ratios and identities, and see what you can do with it.

Answer 2

\[\csc(x) = \frac{ 1 }{ \sin(x) }\] ratios as such and identities as \[\sin^2(x)+\cos^2(x) = 1\]

Answer 3

have you tried to work it out? :)

Answer 4

I did
\[\frac{ \cos (x) }{ \frac{ 1 }{ \cos (x) }*\frac{ \sin(x) }{ 1 }}\]
and ended up at \[\cos^2x*cscx\]
lol

Answer 5

that's a great start!
So let me just write out what you've done so far so we can see where to go from there.
