Answer 7

You changed your mind, Hero.

Answer 8

wats goin in ur mind

Answer 9

No, I wanted to post the mathnotes site for a reason.

Probably a fail then. ^^ LOL

Answer 13

What if he walks on mud on the way to school and then it rains? Formulas are gonna be smudged.

Answer 14

ya

Answer 15

for me i just remember five common derivatives
\[\large x^n \implies nx^{n-1}\]
\[\large e^x \implies e^x\]
\[\large \sin x \implies \cos x\]
\[\large \cos x \implies -\sin x\]
\[\large \ln x \implies \frac 1x\]
^that's for derivatives
then i also remember chain rule, product rule and quotient rule

usually...these 5 derivatives are all you need to pass the course..everything else you can just derive using rules and those common derivatives

Answer 16

I'd say group like formulas together. (e^x)' and (a^x)' g hand in hand, for example.

Answer 17

plss help me frnds m fed up ..

Answer 18

thx ..

Answer 19

as for integrals i just remember the inverse of what i said above \[\large x^n \implies \frac{x^{n+1}}{n+1}\]
\[\large \sin x \implies -\cos x\]
\[\large \cos x \implies \sin x\]
\[\large \frac 1x \implies \ln x\]
\[\large e^x \implies e^x\]
then i rememr u-sub, integration by parts, partial fractions and trig sub

Answer 20

pardon the lack of notations...im kind of lazy to write long notations over and over lol
