Find cot θ if csc θ -(sqrt 37)/6

OpenStudy (amorfide):

you know that cotx is cosx/sinx and you know that cosecx is 1/sinx so knowing that, you should be able to do it

OpenStudy (anonymous):

would it be 1/6

OpenStudy (anonymous):

or just sqrt of 37

OpenStudy (anonymous):

please help me

OpenStudy (amorfide):

look at the formula sin^2x+cos^2x=1 if you work from that you end up getting 1+cot^2x=cosec^2 cot^2x=cosec^2-1 square root both sides gives cotx

OpenStudy (mathmale):

jzamora, I didn't realize you had left our unfinished discussion. Perhaps you can find others to help you instead of me.

OpenStudy (anonymous):

ok so how would i go on?

OpenStudy (amorfide):

To get cot^2x you need to find what Cosec^2x -1 is work out cosec^2x by squaring the value you are given subtract 1 then square root to get 2 answers

OpenStudy (anonymous):

ok so i got 6? is that right?

OpenStudy (anonymous):

i don't think its right

OpenStudy (amorfide):

1/6

OpenStudy (amorfide):

is correct
