Hi Peter,

Try FindRoot. For instance,

eq = 1/2 + c + g*(1 - p) + Sqrt[c + p*g - 1] == 0;

FindRoot[eq /. {c ->  0.1, g ->  0.5}, {p, 4}]

{p ->  4.54164}

Have fun, Alexei


Hi,
Does anybody have a good idea on how to set up and run simple
numerical simulations in Mathematica?

I have an equation that consists of the variables p, g that I want to
solve for p for different values of g=[0,1] and c=[0,1]. The function
could be for example 1/2+c+g(1-p)+root(c+p*g-1)=0. (the real equation
is to complex to solve algebraicly using Solve[XX,p]).

I guess I need to construct a matrix for different values [0,1] of g
and c and then use this to numerically solve for p. but how do i set
this up in a smart way? And how do I use the results to plot p as a
function of for example g?

Best,
Petter
