2 / | | 1 | ----------- dx | _________ | \/ 5*x - 1 | / 1
Integral(1/(sqrt(5*x - 1)), (x, 1, 2))
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 2*\/ 5*x - 1 | ----------- dx = C + ------------- | _________ 5 | \/ 5*x - 1 | /
Use the examples entering the upper and lower limits of integration.
