Best ResponseYou've already chosen the best response.0First, simplify. Then you should just be able to use the power rule for antiderivatives.

Best ResponseYou've already chosen the best response.0then how do you find the original function if you can't integrate

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

Best ResponseYou've already chosen the best response.0Haha. I'd be able to understand how to solve this problem if only i could make out jishan's writing =_=

Best ResponseYou've already chosen the best response.0\[\large f(x)=\int\limits\limits (12x^2+8)(2x^24x)+(4x^3+8x)(4x4) dx\] \[=\int\limits\limits (4 x4) \left(8 x4 x^3\right) \, dx+\int\limits\limits \left(812 x^2\right) \left(2 x^24 x\right) \, dx\] Expand and integrate using power rule for each term \[\int\limits x^ndx=\frac{x^{n+1}}{n+1}+c\] \[f(x)=\left(8 x^5+16 x^4+16 x^332 x^2\right)+c\]

Best ResponseYou've already chosen the best response.0You 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.

Best ResponseYou've already chosen the best response.0If 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.

Best ResponseYou've already chosen the best response.0I am not allowed to integrate whatsoever for this question !!

Best ResponseYou've already chosen the best response.0I'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.

Best ResponseYou've already chosen the best response.0"... 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.
