Hi,
I want to solve equations (1) and (2) to obtain the values of certain quantities, for example x and f. In fact, both equations must be satisfied simultaneously for \tau and f. Since there are other parameters in these equations (for example \tau, M, etc.), and I do not know the optimal values of these parameters, I would like to solve equations (1) and (2) over given ranges for tau, M, and so on. I know that I should use loop commands, but I keep encountering errors. Please guide me.

Hi
I want to plot M versus R=kappa for the mentioned parameters. (I know M must be a real and positive number)
But I couldn't. May someone please review and fix my uploaded file?

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.
