I need help understanding some things with trig can please help. 

Factor the trig expression and simplify:
sin^2x+sin^2x+cot^2x

welshfella · Answer

well you can add the 2 like terms 
sin^2 x + sin^2x + cot^2 x = 2sin^2 x + cot^2 x

anonymous · Answer

oh I totally didnt notice that thank you

welshfella · Answer

that as far as you can go ,  I think

anonymous · Answer

Its multiple choice and thats not one of the choices so it has to simplify furter

anonymous · Answer

I think I got it let me draw it out one second

welshfella · Answer

hum  i cant see how
have you got the choices?
maybe i missed something

anonymous · Answer

never mind I was thinking about something else:/

anonymous · Answer

Its a work sheet and it says the answers could be sin^2x+1 or 1 or cot^2x+1 or cot^2x-1

welshfella · Answer

r u sure its cot^2  x and not cos^2 x?

anonymous · Answer

yes im sure

welshfella · Answer

because sin^2 x + cos^2 x = 1

anonymous · Answer

I know I wish it was that simple but my teacher is mean lol

anonymous · Answer

Can I make cot tan by flipping it

anonymous · Answer

Or do I need common denominators to add?

welshfella · Answer

you can write it as

2 sin^2 x +  cos^2 x
                    ------
                     sin^2 x
but i dont think that helps much

anonymous · Answer

If I flip 2sin^2 it makes it csc and one of the identities is 1+cot^2=csc^2 would that help?
