 Author Comment/Response D. John 01/27/11 10:15pm Hello, I've looked through the help files, and I was wondering if there was any way to Solve a defined function as there is in Maple. I'm doing problems with Mueller's method and I'm attempting to use Mathematica like so: f[x_]:=x^4 + 5x^3 - 9x^2 - 85x - 136 P[x_]:=a*(x-p2)^2 + b*(x-p2) + c NSolve[{P[p0]==f[p0], P[p1]==f[p1], P[p2]=f[p2]},{a,b,c}] The only output I get from the above is {{}}. However I can do the above in Maple. Is there any way to do it in Mathematica, or am I stuck having to first evaluate my P[x] function by hand and then using NSolve? Thanks! URL: ,
