Question

How do we factorize this? I'm confused. sin^2 (x) + 2cos (x) + 2.

Answer 1

are you trying to solve for x? you probably gotta use some identities

Answer 2

And you may wish to remember that \(\sin^{2}(x)+\cos^{2}(x) = 1\)

Answer 3

which is another way of saying you can replace \(\sin^2(x)\) by \(1-\cos^2(x)\) and end up only with cosine

Answer 4

you got that?

Answer 5

Yes sir. Thank you all for clarification. Such simple answer, yet I was hung up.
