Let f(x)=k/(x^3+x) if x>=1, and f(x)=0 otherwise where k is const. (a) For what value of k is f a probability density function? (b) Find the mean of this density function. I'm having a hard time finding my limits of integration, I think it's 1 to infinity. But if that's the case I end up with: k[ln(x) - (1/2)ln(x^2+1)] from 1 to infinity which looks like k(infinity - infinity) - k[0-(1/2)ln(2)] and... i'm lost.
