Re: [Axiom-mail] Problem with integrate

[Nicolas Robidoux]

Looks like a bug to me.

Hi,

I am really new to Axiom. I downloaded it in order to try it with the following
integral. I have here three commands (see below):
  * definite integral between 0 and 1
  * symbolic integration
  * derivative of previous output (which doesn't match my input)

What am I doing wrong? Best regards, tb.

integrate((16*x^14-125*x^10+150*x^6+375*x^2)/(256*x^16+480*x^12+1025*x^8+750*x^4 +625),x=0..1)
