My experiment:
(%i1) f(t):=''(integrate(1/(sin(x)^2+log(x)),x,1,t));
t
/
[ 1
(%o1) f(t) := I ---------------- dx
] 2
/ sin (x) + log(x)
1
(%i2) f(5), numer;
5
/
[ 1
(%o2) I ---------------- dx
] 2
/ sin (x) + log(x)
1
It seems that (%i1) correctly define a function f(t) and maxima is
indeed able to derive it. Why (%o2) does not give a numeric
approximation of f(5)? What I have to do to get it? How can I plot f?
