## anonymous one year ago csc(x)cot(x)(1-cos^2(x))=___x Can anyone help me?

I'm not sure how to use identities to solve this, but that seems to be what it is asking me to do. If anyone can show me step by step how to solve this it would be great.

I think I have gotten to $1/\sin(x)((1/\cos(x))-\cos(x))$

Okay I get that so why can I cancel out the sin?

I understand the replacing with the identity but I'm not sure what you did other than that

Oh wait! So does that mean all I have left is just cos? So I cancel them out from numerator to denominator to get cos(x)? @Loser66

yup

Okay thank you very much!
