## anonymous one year ago Trig /Pre Cal/ identities Does this equal each other? $1-cos x = sin x$ I know $1-cos^2 x - sin^2 x$ does it work the same way??

Was suppose to be Trig /Pre Cal/ identities Does this equal each other? $1-cos x = sin x$ I know $1-cos^2 x = sin^2 x$ does it work the same way??

$\large\rm 1-cos x \cancel= sin x$ 1 - cos^2 x = sin^2x
