Plot Definition and 658 Threads

Hi PF! I have a series of calculations I'm executing in Mathematica, and all expressions use the delayed := equality. At the end I am trying to plot a function, and for this example let's say it's f[x_]:=x When I plot, I am forced to plot in the form Plot[f[x]/.x->y , {y,-1,1} This method takes...

Hi PF! I have the following in Mathematica. Notice h[2,x,0.5] gives me an output in terms of x, but when I try to plot this I get errors. Anyone know why this is? I read the error messages but am still unsure why I am not getting a clean output.

Hi all, I have a spatial probability density function that is dependent on ##x##, space and ##t##, time. I am able to make a plot for spatial probability density for each point in time by specifying ##t## values by using the fplot function. However, I want an animation that allows me to see...

Hi there. I am willing to plot a function of three space variables plus time, let's say ##\phi(x,y,z,t)##. The idea is to plot the 3D function for each time, i.e. evolving in time. As I have three independent variables, corresponding to the three Cartesian coordinates, the function is actually a...

Hi how can i plot a curve (red curve at this example) like this:

Context: In James Hartle's Gravity, pp. 318-319, Example 15.1, he considers the case of a particle that starts falling from infinity into a Kerr black hole, initially with no kinetic energy (e = 1) and initially moving radially (ℓ = 0). The particle's motion is constrained along the equatorial...

Maybe this is more quantum, but I'm not sure. I was watching Susskinds first String lecture on youtube, and he was talking about how, within each particle family, you get a straight line called a regge trajectory if you plot spin vs. mass^2. He also mentioned that there was some slight insight...

I was given a function that is periodic about 2π and I need to plot it. I was wondering if there is a way to input a value and have mathematica generate a new graph with the number of iterations. The function is: $$\sum_{n=1}^{N}\frac{sin(nx)}{n}$$ where n is an odd integer. I guess a better...

This is a plot for understanding the stability of flows through the orr sommerfeld equation. However, I find it really hard to understand. The plot by itself is a little weird, what is it trying to convey?

The wave function is an exponential function, if I plot the real part of it, I don't get a wave graph like sine or cosine function, Why the wave function is not represented by a trigonometric ratio instead. Also, the wave function cannot be plotted since it is imaginary, why is it imaginary? Thanks
