how do I really unassume a variable in Maple?
Hello everyone, thanks for your help in advance!
To perform the integral of this function over rho:
>f1 := alpha*(3*lambda^3*rho*d/(rho^2 + d^2)^(5/2));
I need to assume the variable (d > 0): so,
>assume(d > 0);
>I1 := int(f1,rho=a..b);
>I1;
3 2 2 (3/2) 2 2 (3/2)
alpha lambda d~ (-(b + d~ ) + (a + d~ ) )
- -----------------------------------------------------
2 2 3/2 2 2 3/2
(a + d~ ) (b + d~ )
but I cannot now plug in real numbers for d in I1 (e.q. d := 3.0). I get the same I1 expression as above, with d~. I tried unassume(d > 0), but it did not help. Anyway, thanks for your help.
