Hi, Calculus is about logic & it's great because

if you figure out the underlay of specific things

you can sidestep memorizing a heckload of

information.

To me the only hard thing is finding thesetricks,

I'm specifically having a problem with integrating

inverse trigonometric functions.

For taking the derivative it's simple,

and voila!

No memorizing whatever it is that litters up

the engineering book I foolishly bought.

However, for integrating these functions I don't see

the easy process.

Like, there are 6 functions all differing very slightly

and there's no way I'll be able to memorise them.

Every source I've checked tells me that because I know

the derivatives I can just reverse the process & copy

the form & write the integral. Yay!

Except, I'd have to go through up to a possible 6 side

calculations of derivatives to search out which

form my current integral is in so I can just magially

copy it.

Is there no better way than rote memorization?

Is there no simple logical model to follow that

generalizes to all 6 functions like taking derivatives

of them all has?
