Can this kinda chain help? sin(x)  cos(x)  sin(x)  cos(x)  SIN(X)

there 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

Yeah, but where's the tan(x)?

cos = sin ^

ive 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

Hmm... okay.

But still, is there a way to memorize all of this stuff?

do lots of problems. Eventually you'll memorize them because you see them so often

How about the sec and cosec?

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

You can refer to such thing, bind sin and cos, tan and sec, cot and cosec. They are together in different formulas.

I would really like to know this too. Memorizing diff trig variables.

just 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

I'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!

Hmm. I'd try that way. Thanks @calculusfunctions
