Question

simplify equation below/

Answer 1

\[\sqrt{\frac{ (1-\cos \theta)(1+\cos \theta) }{\cos ^{2}\theta }}\]

Answer 2

I got sin theta

Answer 3

hmmm I got smth else

Answer 4

its =tan theta

Answer 5

?

Answer 6

\[(1-cosx)(1+cosx)=1-cos^2x=sin^2x\]
So we have \[\sqrt{\frac{sin^2x}{cos^2x}}=\sqrt{tan^2x}=tanx\]
Switch the x's to theta. I just forgot how to write theta in latex

Answer 7

oh wow -.- sorry haha that one wasn't hard... I had a brain fart

Answer 8

Ya i get it all the time
