Hi,
I have a function "w" that the eval command does not gives the correct value of its first derivative at a fixed point. I guess the problem is due to sqrt() terms, but I can't fix it.

Hi,
I want to find (w/k)^2 from the following Eq. by Maple. How do I do it?
(u0b, mu,deltab,sigma and A are fixed parameters)

Hi,
I want to have the value of the following two integrals numerically for any arbitrary value of kc  and kh. (Physically the answers of the integrals should be real.)
Is it possible to obtain the analytical solution of these integrals with Meple, in terms of parameters kc, kh, deltac, deltah and sigma ?
Thanks
