Math help! (Trigonometry)
« on: April 27, 2012, 02:56:56 AM »
any tips on solving "Proving of Identities" equations? it's reaaally hard :-\

a.) 1 + sin x    =   cos x
       cos x           1 - sin x



b.) sin^4 t - cos^4 t = 2sin^2 t - 1



(Do i need to practice my algebra on this?)

It looks like you got hit in the face with that egg and you want to eat it too.
