If you do not understand what Jordi means just try this (using his
definition of f)

t=linspace(.01,1,1e3)'; plot(t,f(t))

If you are doing numerical calculus to understand/study real life
phenomena, you may not need infinite resolution and you can use a
smoothed version of your function. If you want "exact" mathematics you
will need a lot of iterations for your numerical scheme... if the
integral exits...
