1 / | | _______ | \/ y + 1 dy | / 0
Integral(sqrt(y + 1), (y, 0, 1))
Let .
Then let and substitute :
The integral of is when :
Now substitute back in:
Now simplify:
Add the constant of integration:
The answer is:
/ | 3/2 | _______ 2*(y + 1) | \/ y + 1 dy = C + ------------ | 3 /
___ 2 4*\/ 2 - - + ------- 3 3
=
___ 2 4*\/ 2 - - + ------- 3 3
-2/3 + 4*sqrt(2)/3
