Question

verify. cos^2x-sin^2x/cos^2x+sinxcosx=1/tanx

Answer 1

take cos x common from denon and see if it works ?

Answer 2

would be wonderful if this was rewritten to show how the fractions look like

Answer 3

\[\cos ^{2}x-\sin ^{2}x \div \cos ^{2}x + sinxcosx = 1/tanx\]

Answer 4

there's also a button in the equation editor for fractions...you might want to use that

Answer 5

nevermind I figured it out :) thanks though!

Answer 6

\[CosxTan ^{3}x = SinxTan ^{2}x\]
