Does anyone else constantly screw this up? And does anyone have practice problems...so i cant stop confusing everything?

 

[Stan..]

Text Book?

 

[DistantCube]

Just remember your rules and use your textbook to practise them, sorry I can't offer more help than that, but if you get stuck on a question, if you post it here I'll try to help, and I'm sure others wouldn't mind helping you out either.

Stan.., your avatar makes you look like an evil sliderule or something.

yeap i think so too
hahaha
i had dat in my mind, but didn't bother to say lol

Same thing came to my mind too....

Back to what d_a_n_z originally asked:
It's a matter of practising different questions...the ones you're most likely to confuse when differentiating/integrating are the trig functions - other than that, I don't think you should have too many problems.

Great minds I suppose...

Yes... if great minds thought alike, then intellectual property lawyers would rule the world.

dont they?

Here are some practice problems for you:
1. Differentiate x^2
2. Integrate x^2




Answers:
(1) 2x
(2) (x^3)/3 + k

they only way to do well is practice, practice, practice, practice, practice, practice....

do the 100 integrals from croneos

+ K? we've been taught + C not + K.... constant?? yeh?

 

[ishq]

when intergrating sine -----> minus sign
when differentiating cos ------> minus sign

i get that wrong constantly

 

[Will Hunting]

Lol, my teacher says whenever the question has a "c" in it (i.e. cos), the answer will be "contrary" (which means opposite sign, according to him) - then he started singing that nursery rhyme, "Mary mary quite contrary... blah blah" and told us to remember it that way

 

[MuffinMan]

o wells i just learnt than intergral dx/ f(x) = intergral 1/f(x) dx lol
didnt realise that for 4 weeks

- hmm, whatever works I guess
I just "anti-derive" in my head to figure it out, but then again I still make careless errors.

Is the imaginary unit i or j? It doesn't matter. Mathematics is based on context - usually not too heavily; just enough to ensure there's no ambiguity.

 

[wrong_turn]

i just remember it as opposites:

ie. differentiation is making the power less and integration making the power more.

so a way to make it visually appealing would be:

integration --> adding to the power

differentiation --> subtracting the power

well as study can be applied, whatever works for ya mate!
