tan^4 x + tan^2 x+ 1 = 1 - (Sin^2 x)(Cos^2 x)
Please someone help me solve this one so I can get some sleep tonight! I've been trying for 3 days off and on. Pretty please!

This identity is false. Are you sure you copied it correctly?
tan^4Ө + tan^2Ө + 1 = 1 + (sin^2Ө)(cos^2Ө) Here it is, pasted directly from the homework. If it's false, I will be relieved. Is there a way to prove that it's false? Carol
