Hi (intetral sign) 1/ (1+ 2^(1/2)) dx I subsituted u= 1 + 2^(1/2) but got no where after du = x^(-1/2) dx Algebraic help or hints please.

is a constant. What does that tell you about its antiderivative?
Maybe have a closer look at your quesiton as,
I am so sorry that I incorrectly posted the problem. I should of taken the time to double check instead of wasting your time. The question is ∫ 1/ (1 + √(2x) ) Again I substituted 1 + √(2x) and got stuck with du = 1/√(x)
. Therefore . Now let so that so that . Now long divide to get .
Shorter way: let , then . We have then . But from , we get . So we have As , this is .
