Bugs in the Integration Function

[Former user]

I have found these bugs while trying to implement the library, and verified them by using the Online Demo. I will state what commands would be needed to be entered into the Demo in order to replicate the bugs as well as the results.

#1 Input : Integrate(e^(x^2+2x+3)(2x+2),x) Expected Output: x^2+2x+3 Actual Output: Error: The function: Delete[1/4Log[e],iv$3] has wrong argument iv$3 at position:2: Trying to convert the argument into the integer range: -2147483648 - 2147483647

#2 Input: Integrate((x^2+1)/(x^3+3x),x) Expected Output: 1/3log(x^2+3) + 1/3log(x) Actual Output: 1/3log(x)

Depends on issue 65.

Rubi rules use the (not yet implemented) assignments:

Plus()=0

and

Times()=1

For Integrate((x^2+1)/(x^3+3x),x) I deleted these rules in the RubI rule set: Deleted Rubi rules

Actually the second evaluation works and the first will be unevaluated:

>>> Integrate((x^2+1)/(x^3+3x),x)
Log(3+x^2)/3+Log(3*x)/3

>>> Integrate(E^(x^2+2x+3)(2x+2),x)
Integrate(E^((x^2+2*x+3)*(2+2*x)),x)
