To Maxima, the symbol 'e' is not in any way special. Say, you used 'a' in
place of 'e'... what would you get if you calculated the integral by hand?
Presumably, you meant to use in place of 'e' the base of the natural
logarithm, the symbol for which is '%e' in Maxima:
(%i1) integrate(%e^(2*x)*cos(1+%e^(2*x)),x);
2 x
sin(%e + 1)
(%o1) --------------
2

Subject: Problems with intergrate
Hi,
I try to integrate a function:
integrate(e^(2*x)*cos(1+e^(2*x)), x);
I calculated it on paper and get:
=1/2 * sin(1+e^(2x))+C
I think this should be the correct. If not blame me!
But maxima calculates this:
sin(e^(2*x)+1)/(2*log(e))
It's nearly the same. but why log(e)? Could you explain how maxima get
log(e) from this intergral?
regards
Andreas
