Surface Area of y=x^3 + 4x

[Roflmao]

I'm finding the surface area of the graph

with the equation for surface area, my work so far is...



arithmetic....



decided that u-sub is the best way to go so...



so the is messing me up right now. what do i need to do to make it go away/cancel out/whatever??

dude
stop posting questions from other sites......

Will you stop it with the copy pasting?

Is it me, or does this kid provide good humor?

i think this kid has some grudge that he has to live up to his brother's standards. Well if that's how it is, do it through hard work, not through copying and pasting pretending to look smart, not saying you aren't, but don't go too far that you seem to have the perception that posting difficult questions makes you look like a genius. I'm not too sure many grade 4 students know the meaning of many of those symbols used let alone the fricken equation. dude i don't think even terrence tao did these in grade four.

It'd be a misnomer to say grade four when referring to Terence Tao, since he was doing year 10 work when he was like 8 (?). By the time he was 10 he participated in the IMO, which has significantly harder questions than this one.

http://en.wikipedia.org/wiki/Terence_tao#Child_prodigy

"Tao was the youngest participant to date in the International Mathematical Olympiad, first competing at the age of ten, winning a bronze, silver, and gold medal respectively. He won the gold medal when he just turned thirteen and remains the youngest gold medallist in the tournament's history."

But, Ahmad, can you honestly describe your brother as being of like ability?
