The area will involve the integral so you need to be able to solve the integral.
Hint: Try substituting in (2 - 1 + 1) and getting your integral in terms -1 + a/(1+2x) dx and consider the derivative of log(1+2x).
In this problem, need to find the area below the function:
in the interval [0,1].
And above the x axis.
I am told there is some logarithms involved here.
After sitting all night....another problem:
Prove that the function has an absolute minimum.
