| Hey guys, I'm currently stuck on this one task where I'm trying to calculate how many solutions the equation A * B = X has, where A is a 3x3 matrix, and B is a 1x3 vector. I'm supposed to use Solve as a command, but I can't get it to work unless I'm... |
| I'm currently trying to learn Mathematica, and I've got some linear algebra tasks to solve with it. I've gotten quite far but now I'm stuck on this one exercise. The instructions are: With the help of Mathematica-commands, draw a new picture,... |
| 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... |
| Hello. I'm spending my friday night trying to learn Mathematica, and so far it's been going decent. This is only my second day using the program, so bare with me. I'm currently on an exercise where I'm supposed to plot these two functions in the... |
| I'm currently stuck on an exercise where I should plot the function: f(t) = sin(30·2?t)+sin(32·2?t) during the interval 0 |
