| Is there a better way of plotting a series of vector points (x,y) than using the Graphics[] command, see attached. I am just trying to visualize all the individual vector points to get an idea of the total graph; however my method seems awful crude... |
| Hi, How would be the preferred way to remove Square Roots in the denominator from a Mathematica answer? After enter v = {1, -1, +1}/Sqrt[(1)^2 + (-1)^2 + (1)^2] Mathematica returns the answer of {1/Sqrt[3], -(1/Sqrt[3]),... |
| Thanks so much, that worked great! Mitch Sandlin |
| Hi; How can I plot or graph a matrix by changing the values of t (time). Each eigenvector makes up a point for x and y, and is proceeded with a constant and suffixed with the eigenvalue. In this example, I would just like to see how the position... |
| Hi; I am trying to graph/plot a 3D object that is created when you rotate y = 1/z, about the z-axes, obtaining the surface of revolution x^2 + y^2 = (1/z)^2. The object looks like a cone with a large base starting on the x and y coordinate plane... |
| Hi; I am having problems getting the answers to computations in the desired units. For example, in Mathematica Input mode, I key Pi/2 + Pi/4 and mathematica gives the answer of (3 Pi)/4 in radians. But what if I want the answer in degrees? So... |
| How would I find the least squares regression line for the 4 given (x,y) points {{-3, 0}, {-1, 1}, {0, 2}, {2, 3}}? I am trying to use the LeastSquares command, but not having much success understanding the documentation and thus getting the command... |
| Actually I am looking for a better way to obtain and then display the data (x and y coordinates) other than hardcoding the x and y coordinates into a Text command. I like the Tooltip command, but even with this command, it seems that you need to... |
| Hi, I am calculating both the amplitude and phase angle in electrical circuits that contain capacitors and inductors. Therefore I need to sum Cos[]'s in Mathematica in which I am having difficulty. Additionally I tried to use Phasor Notation to... |
| Thanks for the reply and your solution works perfectly. However, there still seems to be an inconsistency in the way Mathematica handles variables using the Manipulate command. The section of code I sent you was just a portion of the total code ... |
