1 / | | log(x) | ------------- dx | log(e) | log(7)*------ | log(7) | / 0
Integral(log(x)/(log(7)*((log(E)/log(7)))), (x, 0, 1))
The integral of a constant times a function is the constant times the integral of the function:
Use integration by parts:
Let and let .
Then .
To find :
The integral of a constant is the constant times the variable of integration:
Now evaluate the sub-integral.
The integral of a constant is the constant times the variable of integration:
So, the result is:
Now simplify:
Add the constant of integration:
The answer is:
/ | | log(x) -x + x*log(x) | ------------- dx = C + ------------- | log(e) log(e) | log(7)*------ | log(7) | /
Use the examples entering the upper and lower limits of integration.
