1 / | | 1 | ------- dx | 7*x - 8 | / 0
Integral(1/(7*x - 8), (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 is .
So, the result is:
Now substitute back in:
Now simplify:
Add the constant of integration:
The answer is:
/ | | 1 log(7*x - 8) | ------- dx = C + ------------ | 7*x - 8 7 | /
-log(8) -------- 7
=
-log(8) -------- 7
-log(8)/7
Use the examples entering the upper and lower limits of integration.
