(_____)^2 = (csc x1)(csc x+1)
What is suppose to be in the blank?
***I know this is a trig identity and do not have my sheet with me. No online refrences are helping me***

Best ResponseYou've already chosen the best response.0I know it has to be either tan x or cot x. My memory is not on my side today.

Best ResponseYou've already chosen the best response.1ok.. there are three trig identities. the most common is \[\cos^2x+\sin^2x=1\]

Best ResponseYou've already chosen the best response.1let's solve the right hand side of the equation to see who is the culprit lol xD so we expand \[(cscx1)(cscx+1)\]

Best ResponseYou've already chosen the best response.1just use foil ... you will notice that O and I cancel out

Best ResponseYou've already chosen the best response.1\[(cscx1)(cscx+1) = (cscx)(cscx)+(1)(cscx)+(1)(cscx)+(1)(1)\]

Best ResponseYou've already chosen the best response.1\[(cscx1)(cscx+1) = (cscx)(cscx)+(1)(cscx)+(1)(cscx)+(1)(1) = (cscx)^2+cscxcscx1\]

Best ResponseYou've already chosen the best response.1do you remember \[1+\cot^2x = \csc^2x ? \]

Best ResponseYou've already chosen the best response.1what do I need to do have \[\cot^2x \] by itself

UsukiDoll

Best ResponseYou've already chosen the best response.1yes subtract on both sides..

Best ResponseYou've already chosen the best response.0Oh ok! So we just proved that cot^2 (x) is my answer right?

Best ResponseYou've already chosen the best response.1\[\cot^2x = \csc^2x1\]

Best ResponseYou've already chosen the best response.0Would I just write it as cotx?

Best ResponseYou've already chosen the best response.1huh? you mean for (cotx)^2 = (csc^2x1)

UsukiDoll

Best ResponseYou've already chosen the best response.1hmmm... if you don't forget this part \[\cot^2x = \csc^2x1 \]

UsukiDoll

Best ResponseYou've already chosen the best response.1\[(cotx)^2 = (cscx)^21\] means the same

Best ResponseYou've already chosen the best response.1just don't write cot2x and csc2x1 BIG NO NO!

Best ResponseYou've already chosen the best response.0if u observe the RHS, u see it results csc^21 there is also an identity saying that, cosec^2cot^2=1 that implies cosec^21=cot^2...therefore theRHS is cot^2 therefore obviously LHS must be cot^2...therefore the answer is cot

Best ResponseYou've already chosen the best response.1the term cosecant isn't used for the Pythagorean identities.

Best ResponseYou've already chosen the best response.1but there is one identity that is used beyond trig and that's the \[\cos^2x+\sin^2x = 1 \]
