## anonymous one year ago Which expression is equivalent to sin2x−sinx−2/sinx−2 ? sin x + 1 sin x − 1 sin2x -sin2x

1. UsukiDoll

I'm a bit confused... for the sin2x part is it really sin2x or (sinx)^2 -> sin^2x

2. UsukiDoll

$\large \frac{\sin^2x-sinx-2}{sinx-2}$ like this?

3. anonymous

yes sorry

4. anonymous

i get a decimal but there isn't decimals

5. UsukiDoll

yeah that would work... it's just like factoring only with trigs attached to it $\large \frac{(sinx-2)(sinx+1)}{sinx-2}$ cancel like terms and see what happens

6. anonymous

sinx+1

7. UsukiDoll

:) yes
