Sagot :
[tex]tan(x)=sin(x)/cos(x) the cos(x) would be cancelled out dude[/tex]
tanxcosx=sinx
(since tan=sin/cos) based on its trigonometric basic identities
sinx/cosx X cosx=sinx
sinxcosx/cosx=sinx
(cancel cosx)
sinx=sinx
(since tan=sin/cos) based on its trigonometric basic identities
sinx/cosx X cosx=sinx
sinxcosx/cosx=sinx
(cancel cosx)
sinx=sinx
