Question

1-(cos^(x))/(1+sin(x))

Answer 1

i need help simplifying this. i have a photo to match the problem

Answer 2

except the cos should be cos^2

Answer 3

i thought i answered this. oops i was wrong sorry. numerator is
\[sin^2(x)\]

Answer 4

can you see the attachment?

Answer 5

how did you get that answer?

Answer 6

\[{1-\cos^2x \over 1+\sin x}?\]

Answer 7

no, its 1- the entire fraction i guess cos^2x/1+sinx

Answer 8

ahhhhhhhh

Answer 9

so numerator is
\[1-sin^2(x)=(1+sin(x))(1-sin(x))\]

Answer 10

cancel with the denominator to get
\[1-sin(x)\]

Answer 11

Oh I see. So it's \(1-\frac{\cos^2x}{1+sin x}\).
\[=1-{1-\sin^2 x \over 1+\sin x}=1-{(1+\sin x)(1-\sin x) \over 1+\sin x}=1-1+\sin x=\sin x\]

Answer 12

and \[1-(1-sin(x))=sin(x)\]
