I am trying to evaluate a definite integral using SAGE and am getting
some errors. I have evaluated the same integrals using Mathematica
without a problem. Here is the integral in question:
integral(0.298321984000000/((13.1233333333333*X + 1)^2*
(15.7466666666667*X + 1)),(X,0.05,0.3))
I get the following error:
Inverse of zero divisor?
I then tried using the numerical_integral command:
numerical_integral(0.298321984000000/((13.1233333333333*X + 1)^2*
(15.7466666666667*X + 1)),(X,0.05,0.3))
for which I get he following error:
TypeError: unable to simplify to float approximation
The syntax for numerical_integral is different than the syntax for
integral (in particular, you don't specify the variable or the range in
parentheses). This works:
sage: var('X')
X
sage: numerical_integral(0.298321984000000/((13.1233333333333*X +
1)^2*(15.7466666666667*X + 1)),0.05,0.3)
(0.0033064907013495063, 3.6709421073472043e-17)
The first number is the result, the second is an error bound.
Thanks,
Jason
