but how is that possible that its a  cos A ? I dont see it

 (sin Acos A) = sin A (cos A) = sin A +cos A = cos A sin A

ok , lets forget everything, lets go another way. can u separate out the denominator ?

hartnn Group TitleBest ResponseYou've already chosen the best response.0
like (a+b)/c = a/c + b/ c

lilsis76 Group TitleBest ResponseYou've already chosen the best response.1
i 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

hartnn Group TitleBest ResponseYou've already chosen the best response.0
absolutely correct! whats sin A/ sin A =? and cos A/cos A = ?

lilsis76 Group TitleBest ResponseYou've already chosen the best response.1
there going to equal 1

hartnn Group TitleBest ResponseYou've already chosen the best response.0
so u got 2 right ?

lilsis76 Group TitleBest ResponseYou've already chosen the best response.1
what? well if u add them 1 + 1 = that makes 2
 2 years ago

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

oh shoot. thats right... okay because it was a negative the answer will be negative too.

makes sense ?

ya 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?
 2 years ago

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

okay, ya thats what i thought :)

dw:1349294542963:dw what is 1/sin a and 1/ cos a ?
 2 years ago

lilsis76 Group TitleBest ResponseYou've already chosen the best response.1
the 1/ sin a = the inverse of cos. that is csc and 1/ cos a = is the inverse of sine sec
