Best ResponseYou've already chosen the best response.0Can this kinda chain help? sin(x)  cos(x)  sin(x)  cos(x)  SIN(X)

Best ResponseYou've already chosen the best response.0there is no easy way. it comes with enough practice and problems. Thats how i got them. sin=cos, cos=sin, tan = sec^2, sec = sec*tan...thats what i know...the other 2 dont get used that often. the chain/circular reference does kinda work

Best ResponseYou've already chosen the best response.0Yeah, but where's the tan(x)?

Best ResponseYou've already chosen the best response.0And the hyperbolic ones?

Best ResponseYou've already chosen the best response.0ive never had to use the hyperbolic ones, and the inverse ones (i.e. sin^1) are very difficult to memorize because they all look the same

Best ResponseYou've already chosen the best response.0But still, is there a way to memorize all of this stuff?

Best ResponseYou've already chosen the best response.0do lots of problems. Eventually you'll memorize them because you see them so often

Best ResponseYou've already chosen the best response.0How about the sec and cosec?

Best ResponseYou've already chosen the best response.0sec = sec*tan, csc = cscx*cotx. theyre basically opposites, so if you know sec, you can get csc

Best ResponseYou've already chosen the best response.0You can refer to such thing, bind sin and cos, tan and sec, cot and cosec. They are together in different formulas.

Best ResponseYou've already chosen the best response.0I would really like to know this too. Memorizing diff trig variables.

Best ResponseYou've already chosen the best response.1just remember: derivative of a cofunction is negative i.e. d/dx of cos x is sinx d/dx of csc x is csc x cot x d/dx of cot x is csc^2 x

Best ResponseYou've already chosen the best response.2I've never had to memorize them. After doing them a few times, you just know them. I'm only speaking for myself, but I just know all the differentiation rules, trig identities by heart. Actually pretty much any formula, I've never had to really memorize, but rather just understand the justification behind them. I can't explain it but I pretty much know any mathematical formula, rules, etc, by heart. I guess that's why I love MATH!

Best ResponseYou've already chosen the best response.0Hmm. I'd try that way. Thanks @calculusfunctions
