| Hi, I am solving a system of two equations, but the equations themselves change depending on whether one parameter is positive or negative : for x0 0 sol[i1_?NumberQ, i2_?NumberQ, z0_?NumberQ, x0_?NumberQ] :=FindRoot[{i1 == f1[z, x], i2 ==... |
| Thank you. My problem is somewhat different and I could not figure out how to apply your solutions to my case sol[p1_?NumberQ, p2_?NumberQ, p3_?NumberQ, p4_?NumberQ, p5_?NumberQ] := FindRoot[my equations, {{z, p5}, {x, 5}}]; And then... |
| Thank you, that has worked! |
| Thank you for your suggestions. They gave me some idea but there is still one thing that I can't figure out. In the examples you gave the values of k are entered explicitly by hand. But in my case the parameter k (in fact, not just one k but 4... |
| It seems I've found the answer on the Web. For a numerical solution of non-polinomial equations one should use FindRoot instead of Solve or NSolve. I am having some other trouble with FindRoot too but, I think, I should post a different question for... |
| Hi We've been trying to contact Wolfram to purchase Mathematica license for our organization however we could not get any response. Does anybody have an idea? Is there anything wrong with the company or do we misunderstand something about the... |
| Thanks a lot! This was very helpful. Now I see that I can get the solution I need with Mathematica |
