Question

surface area integration

Answer 1

\[y=2\sqrt{x+1} for 1 \le x \le 10\]

Answer 2

\[\int\limits 2 \pi f(x)ds\]

Answer 3

\[4 \pi \int\limits \sqrt{x+1}\sqrt{1+\frac{ 1 }{ x+1 }}dx\]

Answer 4

so I combined the fraction and canceled out the x+1s and got\[\int\limits_{1}^{10}\sqrt{x+2}dx\]

Answer 5

but when I compute this it is not the same answer I get for the original integral.

Answer 6

nvm got it
