Best ResponseYou've already chosen the best response.0 (sin Acos A) = sin A (cos A) = sin A +cos A = cos A sin A

Best ResponseYou've already chosen the best response.0ok , lets forget everything, lets go another way. can u separate out the denominator ?

Best ResponseYou've already chosen the best response.1i think i can, but it would be in 4 sections right? like sin A / Sin A  cos A/sinA + cos A/cos A sinA/cos A

Best ResponseYou've already chosen the best response.1what? well if u add them 1 + 1 = that makes 2

hartnn

Best ResponseYou've already chosen the best response.0yes. now u are left with cos A/sinA sinA/cos A cross multiply again, same as previous problem

Best ResponseYou've already chosen the best response.1ya i see it, i under stand it but just forgot where the 2 came from. it came from the 2 fractions that crossed each other out right?

hartnn

Best ResponseYou've already chosen the best response.0it came from sinx/sin x + cosx / cos x = 1+1 = 2

Best ResponseYou've already chosen the best response.1the 1/ sin a = the inverse of cos. that is csc and 1/ cos a = is the inverse of sine sec
