using MATLAB 6.1.0.450 (R12.1) to access the maple
kernel I don't get a solution. for:
int(exp(x)*erf(x),x = a .. b)
Does anyone know if this is solvable? It looks like you could do parts
a few times, and then equate terms. Since:
>> int(sym('erf(x)'))
ans =
x*erf(x)+1/pi^(1/2)*exp(-x^2)
What about the integral:
int(exp(x^2)*erf(x),x = a .. b)
For this I could let u=erf(x)
and do substitution. Right?
Moreover, If I figure out how to do the integral myself, how do I
teach maple to do it?
