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)?

And the hyperbolic ones?

cos = -sin ^
anonymous
  • anonymous
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
ParthKohli
  • ParthKohli
Hmm... okay.

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

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

How about the sec and cosec?
anonymous
  • anonymous
sec = sec*tan, csc = -cscx*cotx. theyre basically opposites, so if you know sec, you can get csc
klimenkov
  • klimenkov
You can refer to such thing, bind sin and cos, tan and sec, cot and cosec. They are together in different formulas.

yup practice

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

would help alot actually

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
