    What is the forumla for intergration again? :confused:

    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]

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

    \Large 

\Bigint (6x^2 \ + \ x^{1/2}) \ dx \\ \, \\



= \ \frac{6x^3}{3} \  + \ \frac{x^{3/2}}{(3/2)} \ + \ c \\ \, \\

= \ 2x^3 \ + \ \frac{2x^{3/2}}{3}  \ + \ c

    if u r talking about the big f : no it's neither an S nor an f, it's ∫ which means INTEGRAL

    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

    6x^3/3 + x^3/2/3/2 + C

    therefore final answer is after simplifying

    2x^3 + 2x^3/2/3 + C

    2x^3 + 2x^3/2/3 + C

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

    just to make it less confusing!

    or indeed,

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

    to make it more!

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

    Computers aren't used to equations

    (except with the exception of Microsoft Equation... which is just awkward... *sigh*)
