Wait are you finding the anti derivative..?

@Luigi0210 yes :S & @jishan i am not allowed to integrate

First, simplify. Then you should just be able to use the power rule for antiderivatives.

then how do you find the original function if you can't integrate

Distrubute and then combine like terms

simplify the function given then integrate to get f(x)

Jhannybean Group TitleBest ResponseYou've already chosen the best response.0
But he says he's not allowed to integrate? That's what's confusing me. how to you find F(x) without integrating?

Haha. I'd be able to understand how to solve this problem if only i could make out jishan's writing =_=

galacticwavesXX Group TitleBest ResponseYou've already chosen the best response.0
i think he simplified the problem but its soo unclear and he also integrated

\[\large f(x)=\int\limits\limits (12x^2+8)(2x^24x)+(4x^3+8x)(4x4) dx\] \[=\int\limits\limits (4 x4) \left(8 x4 x^3\right) \, dx+\int\limits\limits \left(812 x^2\right) \left(2 x^24 x\right) \, dx\] Expand and integrate using power rule for each term \[\int\limits x^ndx=\frac{x^{n+1}}{n+1}+c\] \[f(x)=\left(8 x^5+16 x^4+16 x^332 x^2\right)+c\]

I don't think you can find f(x) without integrating @galacticwavesXX

that's what i was thinking

You don't need to go through anything elaborate, just look at it. It's fairly clearly a productrule derivative, so just take the second part of the first term times the first part of the second term. You can add in a constant for good measure.

If you assume f(x) = g(x) * h(x), then f'(x) = g'(x)h(x) + g(x)h'(x). You can just look at the problem and go from there.

I am not allowed to integrate whatsoever for this question !!
 one year ago

Jemurray3 Group TitleBest ResponseYou've already chosen the best response.0
I'm not talking about any integrating. Look at what I wrote, then look at the question. You can clearly see what h is, and what g is, so you know what f is.

"... are you finding the anti derivative..?" "yes :S" I suppose finding antiderivative is the same as integrating. If you don't like the integral sign, then you may take the limit of a sum: \[\lim_{x\rightarrow \infty}\sum_{k=1}^{n} y(x_k)\Delta x\], which is the same as integrating the function.
