Question

Factor sin(^2)x + sinx -2 in the terms of a single trigonometric function

Answer 1

well this is a quadratic equation where instead of x your have sin(x)

so what are the factors of the constant term, -2 that add to 1

the larger factor is positive.

Answer 2

so the factored form is

(sin(x) + factor 1)(sin(x) + factor 2)

Answer 3

Oh! So it just works out as if it were a quadratic? (sin(x) +2)(sin(x)-1) ?

Answer 4

thats it... easier than it looks...

Answer 5

That's for sure! Thank you!

Answer 6

Just remember: it can be treated like a quadratic, but it isn't one.
