25 / | | 4 | ----- dx | ___ | \/ x | / 9
Integral(4/sqrt(x), (x, 9, 25))
The integral of a constant times a function is the constant times the integral of the function:
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:
So, the result is:
Add the constant of integration:
The answer is:
/ | | 4 ___ | ----- dx = C + 8*\/ x | ___ | \/ x | /
