Question

Integral of 1/ sqrt(1+2x) dx ? Upper limit=12 Lower limit = 0.

Answer 1

1/5 - 1 = -4/5

Answer 2

\[ \int\limits_{0}^{12} 1 \div \sqrt{1+2x}\] this is what it looks like. im getting 8 but the answer is 4 ..

Answer 3

Work:
Upper limit - 1/sqrt(1 + 24) = 1/sqrt(25) = 1/5
Lower limit - 1/sqrt(1 + 0) = 1/1 = 1
Upper limit - lower limit = 1/5 - 1 = -4/5

Answer 4

but the answer is 4 ..

Answer 5

Oh, crap... I forgot how to integrate, lawl.
Let's try that again...

Answer 6

1 + 2x = u
2dx = du
dx = du/2

1/2 * integral(1/rad(u) du)
I think this is it.

Answer 7

Hmm, okay, thanks..
