Simplify the expression. cos x + sin x tan x

OpenStudy (timaashorty):

is it sec x ?

OpenStudy (anonymous):

Yes, yes it is!

OpenStudy (timaashorty):

Thank you Batmaan!

OpenStudy (anonymous):

\[cosx+sinxtanx = cosx+sinx (\frac{ sinx }{ cosx })\]

\[\large \rm \dfrac{adj}{hyp} + \dfrac{opp}{hyp} \dfrac{opp}{adj}\]

OpenStudy (anonymous):

\[cosx+\frac{ \sin^2x }{ cosx } \implies \frac{ \cos^2x+\sin^2x }{ cosx } \implies secx\]

OpenStudy (timaashorty):

I now understand. Thank you both for the help/ explanation :)

OpenStudy (anonymous):

Yeah, just remember the identity cos^2x+sin^2x, so 1/cosx = secx

OpenStudy (anonymous):

cos^2x+sin^2x = 1*
