Hi,

First of all, I'm beginner in Maple. 
I want to plot  "M" versus "kc" and "deltah" as a 3D curve (M is real and positive). Intervals of kc and deltah are  given (see attached file). These three parameters (i.e, M,kc,deltah) should satisfiy the following equation:
Eq=-(1-(deltab+deltah))-(1-(deltab+deltah))/(kc-3/2)-deltah/sigmah-deltah/(sigmah*(kh-3/2))-(1/6)*deltab*sqrt(3)*mu*(1/sqrt((M-u0b+sqrt(3)*sqrt(mu*sigmab))**2)+1/sqrt((M-u0b-sqrt(3)*sqrt(mu*sigmab))**2))/sqrt(mu*sigmab)-(1/6)*sqrt(3)*(1/sqrt((M+sqrt(3)*sqrt(sigmai))**2)-1/sqrt((M-sqrt(3)*sqrt(sigmai))**2))/sqrt(sigmai)=0.

Other parameters are as follows:
 kh=3, sigmah=4,sigmab=1,u0b=0.05,sigmai=1/300,deltab=1e-6,mu=1836.

Hi,
I have a problem and I haven't been able to solve it yet. I want to solve an ordinary diffrential equation similar to
                                                                                                   (dphi/dxi)^2+2*V(phi)=0
and plot phi versus xi for a the following conditions:
1) V(phi)=dphi/dxi=0 at (phi=0,phi_m) and
2) dV(phi)/dphi=0 at phi=phi_m and 
3) d^2V(phi)/dphi^2=0 at both phi=0 and phi=phi_m.
How can I do this by Maple?(see the attached file)

Hi,
I have a function (see attached file).  How can I find by Maple 
those values of beta and f for which W will have 
three consecutive local extrema between the
phi=0 and phi_0 where W=dW/dphi=0 at phi=0 and W=0 at phi_0 and W<0 for 0<abs(phi)<phi_0?
Thanks,

HI,
I want to simplify an algebraic experssion. How do I do this with Maple?

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.
