Question
Again, consider the integral
x In(x) dx.
Since we have already determined that we cannot choose u = x in this case, to use IBP, let's instead choose
u = In(x). Which of the following lists the correct functions for du, du and v in this case?
a. du =
In(x) dx, dv = x dx and v = 1.
%3D
b. du = - dx, dv = x dx and v =
1 2
%3D
c. du = - dx, dv = dx and v = x.
%3D
%3D
d. du = - dx, dv = ;x² dx and v = x.
