Question

Which expression is equivalent to sin2x−sinx−2/sinx−2 ?

sin x + 1

sin x − 1

sin2x

-sin2x

Answer 1

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

Answer 2

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

Answer 3

yes sorry

Answer 4

i get a decimal but there isn't decimals

Answer 5

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

Answer 6

sinx+1

Answer 7

:) yes

Answer 8
