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 is when :
So, the result is:
Now substitute back in:
So, the result is:
Now substitute back in:
Add the constant of integration:
The answer is:
/ | | 2 3 | log (x) log (x) | ------- dx = C + ------- | x 3 | /
3 3 log (2) log (5) - ------- + ------- 3 3
=
3 3 log (2) log (5) - ------- + ------- 3 3
-log(2)^3/3 + log(5)^3/3
