| That doesn't always work, but sometimes it can solve a problem that you can't find any other solution to |
| Usually the & is only used to indicate the end of an "anonymous" function that hasn't been previously defined. You can look up "Function" in the help pages and see what you can make of that. It is sometimes confusing for new users because they are... |
| If I start Mathematica fresh and I click on the menu bar Evaluation->Quit Kernel->Local and click yes I really want to quit the kernel, but that doesn't quit Mathematica, and then I evaluate your project notebook one cell/expression at a time then... |
| Perhaps MatrixForm[RowReduce[m]] and NullSpace[IdentityMatrix[6]] might give a hint |
| If I haven't made any mistakes then your code appears equivalent to this simplified version b = 0.9999998593355306`; ?1 = 0; ?2 = 2 Pi; n? = 40; step? = (?2-?1)/n?; kt[n_] = n*7.729837371051386*^14; g[t_, n_, w_, ?_, ?_] = ... |
| More on a level of superstition than anything else, you might see if you could justify cross multiplying to get rid of those denominators. I have a feeling from some experience that denominators sometimes make finding solutions much more difficult. ... |
| Perhaps Solve for Subscript[w,s] Subscript[w,s]=Subscript[w,s]/.Solve[?*Subscript[a,s](Subscript[a,s]Subscript[w,s]^?)^(?-1)==w,Subscript[w,s]][[1]] and then Simplify for Subscript[m,w] ... |
| This theta = (At100*rc*Pc*MwB)/(3*dbm*Pb*MwC); appears to be causing you problems. If I remove that, then evaluate the rest of your assignments, and finally NMinimize[{Norm[R2]+Norm[R1], 0 0}, {theta, dam, dbm}] quickly returns ... |
| . ... rms = 0; z = Table[ ... rms = Sqrt[(rms^2*(t1/Delta) + iL21^2)/(t1/Delta + 1)]; {t1, iL21, iL11, rms}, {t1, 0, tmax, Delta}]; Show[{ListPlot[z[[All, {1, 3}]], PlotStyle -> Green], ... |
| An alternative method. Look at FullForm[eq1] and find the exact form your expression appears in. This may be different from the displayed form, particularly when there are denominators or negative exponents. Copy the exact form from the... |
