simplify tanx/secx+1

OpenStudy (wilsondanielle):

identities! Start by breaking tan and sec into terms of sin and cos

OpenStudy (anonymous):

(sinx/cosx)/secx+1 as far as i got

OpenStudy (wilsondanielle):

secx = 1/cosx

Directrix (directrix):

Is this --> tanx/secx+1 tanx/(secx+1) OR ( tanx/secx ) +1

OpenStudy (anonymous):

1st one

OpenStudy (wilsondanielle):

substituting in 1/cosx for secx, you should have sinx/cosx /(1/cosx +1) can you see what to do from there?

OpenStudy (anonymous):

multiply reciprocal?

OpenStudy (anonymous):

@wilsondanielle

OpenStudy (anonymous):

have no clue sorry. its 1 am

OpenStudy (wilsondanielle):

it's fine! i would turn the one into cosx/cosx, so it's a common denominator with the other term

OpenStudy (anonymous):

hmm

OpenStudy (anonymous):

so now its (sinx/cosx)/(1/cos)+(cosx/cosx)???

OpenStudy (anonymous):

sinx/1+cosx

OpenStudy (wilsondanielle):

i'm going to try drawing it - don't judge my writing.

OpenStudy (anonymous):

lol ok
