| What specifically is this command for? i don't quite understand what it means. vars = Array[x, 3]; |
| Thank you very much Hans. This has helped me tremendously. |
| I'm trying to set up a change of basis matrix from the base W -> V and then verify that it works by seeing that the co-ordinates on the x-vector changes as they should. I'm supposed to use the *Inverse* function, but I don't know what to do with it.... |
| I'm currently doing some Mathematica exercises, and I'm stuck on this one task where you're supposed to plot the functions h(t)= |3-t^2|+|t-1|-t^2 , g(t)=3sin(t) in the same grap, and then find all the roots. This is what I've got so far: ![enter... |
| Ah okay. The first one is definitely the one I'll be using then. You used -3,1,3 for the interval, why was that? |
| If you look at my edited post, it turns out that I dont have to use Manipulate. I need to decide the frequence of the two superposed oscillations which can be read from the graph. Is that the min, and max value? |
