Prove that the following identity is true:

1 + cos x/1 - cos x=csc x + cot x

prove that the following identities is true:

1 + cot^3 t/1 + cot t=csc^2 t - cot t

Find all solutions if 0 < x< 2pie. Use exact values only.

cos 2x cos x - sin 2x sin x =1/(square root of 2)

Get out your identities and start swapping them in! :)

Get as far as you can then ask us if you are going down the right track.

Spelling pi "pie" makes me angry.

Very angry today, eh capuchin? ;)
