1 / | | 1 | --------- dx | _______ | \/ x + 1 | / 0
Integral(1/(sqrt(x + 1)), (x, 0, 1))
Let .
Then let and substitute :
The integral of a constant times a function is the constant times the integral of the function:
The integral of a constant is the constant times the variable of integration:
So, the result is:
Now substitute back in:
Now simplify:
Add the constant of integration:
The answer is:
/ | | 1 _______ | --------- dx = C + 2*\/ x + 1 | _______ | \/ x + 1 | /
___ -2 + 2*\/ 2
=
___ -2 + 2*\/ 2
-2 + 2*sqrt(2)
Use the examples entering the upper and lower limits of integration.
