I have a question that i am finding a different answer then one given. pleas explain where i am going wrong. given: cosec Theta = a so i know sin = 1/a asked to give remaining ratios. terminates in Quadrant 1 cos = sqrt (1-(1/a)^2) how do they come up with sqrt (a^2-1)/a :oops: i left school too ear...
hmm i see sqrt(1-1) 1/1 *a/a the a going back under the root gets ^2 theirfore sqrt (a^2 -1)....over a+a Denominators = a... simple fraction rules. i over thought that.
