I'm saying how do you get \[1/2\sqrt{2}\]?

jasonxx Group TitleBest ResponseYou've already chosen the best response.1
use pythagoraas....

don't use that....if you have to use that find another side first
 one year ago

asapbleh Group TitleBest ResponseYou've already chosen the best response.0
if so, how do i find the other side?
 one year ago

jasonxx Group TitleBest ResponseYou've already chosen the best response.1
use pythagoras.....as i have stated above

ok, then if i need to find csc theta, if cot theta = 21/20 and sin theta>0 then would my answer be \[\sqrt{1+21/20}\] or

from above triangle cot theta= 2 sqrt 2

im sorry, this is another problem, not the above triangle

i just explained the easiest method to find out any answer

jasonxx Group TitleBest ResponseYou've already chosen the best response.1
see you have sin theta= 1/3 now 1 is perpendicular and 3 is hypotenuse now use pythagoras theorem to find another side and since you have three sides you can find any of the trigonometric value

what another side?
 one year ago

asapbleh Group TitleBest ResponseYou've already chosen the best response.0
I dont seem to have another side
 one year ago

jasonxx Group TitleBest ResponseYou've already chosen the best response.1
another side would be ^2=1^2+x^2 x^2=91=8 x=2sqrt2

Problem: Find csc theta if cot theta=21/20 and sin theta>0 if i use the pythagoreas, then would it be 20^2+x^2=21^2 ?

square both sides. multiply through by sin^2 solve for tan
