# C1 - integration watch

1. What is the forumla for intergration again?

I stupidly differentiated a question when it asked to integrate

Find;

f(6x^2 + x^1/2)dx
[note, the f is that big f looking thing]
2. Integration

But isn't Integration C2???

Add a power, and divide by the new power
If you mean:

4. ok, thanks, so it's;

(ax^n+1)/(n+1) + the stupid c

that right yea?
5. exactly if u mean int. ax^n dx
6. yea, thanks. After a few more practice questions i should be ready for the exams next week . TY
7. Isn't it an s? like, as in sum of all parts from whatever to whatever? oO always looked that way to me

if u r talking about the big f : no it's neither an S nor an f, it's ∫ which means INTEGRAL
9. I know that! It just always looked more like an S to me oO I don't get through C1-4 and FP1-3 not knowing what an integral sign looks like :P

ok. but ya, it looks like an S , and like an f.
11. Well, Ive always thought Italic S, I mean, there no dash across it to be an f :P

I stupidly differentiated a question when it asked to integrate

Find;

f(6x^2 + x^1/2)dx
[note, the f is that big f looking thing]
6x^3/3 + x^3/2/3/2 + C

therefore final answer is after simplifying

2x^3 + 2x^3/2/3 + C
13. 2x^3 + 2x^3/2/3 + C

2x^3 + 2x^(3/2)/3 + C

just to make it less confusing!
14. or indeed,

2x^3 + (2x^(3/2))/3 + C

to make it more!

Yeah, thanks. I am not used to laying out equations on the computer.
16. ya i thought about doing that , but i did after i had already posted, so i felt "lazy" to edit it :P

cheers anyway
17. to make it more and more less confusing: it should be :
2x^3 + [2x^(3/2)]/3 + C

Yeah, thanks. I am not used to laying out equations on the computer.
Computers aren't used to equations

(except with the exception of Microsoft Equation... which is just awkward... *sigh*)
19. I can lay out easy equations like this on a comp all day long.
Matrices, on the other hand, are a *****! =\
20. Agreed, plus they take up alot of space, I'd hate to write exams...
