Question

(WILL GIVE MEDAL AND FAN)
Simplify. (Posting equation below.)

Answer 1

\[\sin x \tan x + \cos x\]

Answer 2

first, simplify sinxtanx.
sinx tanx = sinx * sinx / cosx = sin^2x / cosx

then, add cosx and sin^2x / cosx. how? by making cosx a fraction:
cosx = cos^2x / cosx

(cos^2x + sin^2x) / cosx = 1 / cosx

Answer 3

Thank you! Three more to go. Did you want me to post those as a new question as well?

Answer 4

Sure! Thx... :)

Answer 5

No problem!
