| Hi, I would like to obtain a general solution for x from a second order non linear differntial equation s* x''[t] + x'[t] - C / x[t] = 0 I used the following code in mathematica as suggested in the mathematica help tutorials: ... |
| I would like to solve a differential equation. To find the solution of Xp (or y[x] in the below equation),I tried formulating the equation: DSolve[J*y''[x] + y'[x] -c/y[x]==0 , y[x], x] But, I really don't get a solution.. Not sure what is... |
| Sorry .. but How helpful is that..? i have my own data here.. |
| Hi, Thanks for your response.. in this case I would only like to plot the red dots without highlighting the other black dots... and the red dots that should be on an increasing shade of intensity.. and the x and y intercepts are not the same..... |
| Sorry! I dint follow the code quite well, I tried something like this and it did not work... Cpdata = Table[ solNp = NSolve[(dNpdt /. sol) == 0, Np]; Cp = (a Np (1 + \[Gamma]rs) (-1 + \[Delta]))/( b Np (-1 + \[Delta]) -... |
| Sorry.. but what does the ;; in this comand mean..? ListPlot[points[[;; , ;; ;; 4]], PlotMarkers -> {Automatic, 10}]] |
| Thanks! it helped! I actually did not follow the code well, but it worked on copying and pasting.. How would it be if the colour shading is in the opposite direction? |
| Hi! It doesnt really work.. Got an error saying Unknown option PlotLegends for Panel. >> It doesn't work along when creating a panel :( |
| No, I don't think I am doing it right, I am not getting any plots for it. I dont know how to explain my porblem. may be this is not the right way , but I have attached an example file of what i am doing but a smaller version of it. please ignore the... |
| Hi all, may be i wrong with my title words. sorry for my bad english. But here is the thing, I am using the table function to generate a set of values for a steady state function called Np. With this function i will be generating 5 rows and... |
