For some integer type, how can I find the value that is closest to some value of a floating-point type even when the floating point value is far outside the representable range of the integer. Or ...

I am implementing an algorithm for school and am having problems understanding how a definite integral is represented in programming. For example I know that the Summation equation can be implement...

I'm looking for a solution for a double integral that is faster than integrate(function(y) { sapply(y, function(y) { integrate(function(x) myfun(x,y), llim, ulim)$value }) }, llim, ulim) w...

When I try to calculate the following integral in Mathematica 8, I get this strange result: In[1]:= Integrate[y/((1 + x^2 + y^2)^(3/2)), {y, 0, 1}] Maple 14 can solve this one easily: Why ...

In attempting to use scipy's quad method to integrate a gaussian (lets say there's a gaussian method named gauss), I was having problems passing needed parameters to gauss and leaving quad to do th...
