Numerical Equation Solving?



| Example equation, to solve for "w":
|                                                                                                  
|             12
| 2.1237 = ----------
|         !   2    !
|         !3 w  - 4!
                                                                                                  

One way is to use interpolate. You have to work around the undefined values.

interpolate(2.1237=12/abs(3*w^2-4),w,sqrt(4/3)+.01,10);

interpolate(2.1237=12/abs(3*w^2-4),w,-10,-sqrt(4/3)-.01);

  - 1.793554720803482
