look at the LHS...try factoring out csc^2 what do you get?

not exactly....if you factor out csc^2 then csc^4 becomes csc^2 but csc^2 doesn't become csc^2

Would it even exist, that is, would it cancel? Or just be csc?

what is csc^2/csc^2?

ohhhh. I feel dumb. Got ya.

lgbasalloteBest ResponseYou've already chosen the best response.1
so what should the factored form be?

now what is csc^2  1?
 one year ago

lgbasalloteBest ResponseYou've already chosen the best response.1
so uou have \[\huge \csc^2 (\cot^2)\] now here comes a tricky part...review your identities and give me the equation for csc^2
 one year ago

AmTran_BusBest ResponseYou've already chosen the best response.1
csc2 = 1/sin...it also equals cot+1
 one year ago

lgbasalloteBest ResponseYou've already chosen the best response.1
cot^2 + 1 not cot + 1

AmTran_BusBest ResponseYou've already chosen the best response.1
Sorry, your exactly right.

lgbasalloteBest ResponseYou've already chosen the best response.1
you should check your notes and make sure you wrote them right....you might get them wrong... \[\huge \sin^2 + \cos^2 = 1\] \[\huge \tan^2 + 1 = \sec^2\] \[\huge \cot^2 + 1 = \csc^2\]
 one year ago

lgbasalloteBest ResponseYou've already chosen the best response.1
anyway...back to what i was saying... csc^2 is cot^2 + 1 so \[\huge \csc^2 (\cot^2) \implies (\cot^2 + 1)(\cot^2)\] now expand that

AmTran_BusBest ResponseYou've already chosen the best response.1
would the lhs say csc cot ^4? The RHS is cot^4 +cot^2
 one year ago

lgbasalloteBest ResponseYou've already chosen the best response.1
i think you're confused...let me flip it... \[\huge \cot^2 \theta (\cot^2\theta + 1)\] do you know how to distribute that now?

AmTran_BusBest ResponseYou've already chosen the best response.1
Its not that I'm confused as much as tired my friend. dw:1353026333309:dw

well anyway... cot^2(cot^2 + 1) becomes cot^4 + cot^2 so you have just proven the identity
