Best ResponseYou've already chosen the best response.1for example tanA= sinA/cosA= SinA/sinC/TanA/ TanB see that

Best ResponseYou've already chosen the best response.0They all have tan though :/

Best ResponseYou've already chosen the best response.1yes that is the point because tan is sin/cos

IloveCharlie

Best ResponseYou've already chosen the best response.0Yes but how will I know which one is the answer?

Best ResponseYou've already chosen the best response.1Fun, look at arccos(3/5) and arcsin(5/13) as just numbers because that is what they are so set x = arcsin(5/13 and y = arccos(3/5) and see the identity attached

Best ResponseYou've already chosen the best response.1note in respect to the image x and y are theta

Australopithecus

Best ResponseYou've already chosen the best response.1this problem is just about being able to look up trig identities I dont think you will ever have to memorize these unless you go into majoring mathematics even then I doubt you would ever have to

Australopithecus

Best ResponseYou've already chosen the best response.1well there are some trig identites that are important to know but this one I do not believe is used very commonly in early mathematics courses

Australopithecus

Best ResponseYou've already chosen the best response.1also im sure you can derive this instead of memorizing it but idk

Best ResponseYou've already chosen the best response.1hey charlie I was trying to backwards with you,because sometimes it is easier that way. I don't want to mess you up so please let me know .

Best ResponseYou've already chosen the best response.0@godorovg Oh, it's fine. I just didn't quite understand that way but I appreciate your help. @Australopithecus so... the third oone? I'm trying to match up
