Here's a Kotlin program that uses Java Swing and Java AWT to plot sine and cosine curves for the interval [0,2π]. The program creates a window with a panel where both curves are drawn: Uses JFrame and JPanel for GUI rendering. Uses Graphics to draw the sine and cosine curves. Automatically...

This is my code: import numpy as np import matplotlib.pyplot as plt def sinc(x): return np.where(x == 0, 1, np.sin(x)/x) x = np.linspace(0, 25, 500) # mainly for setting the number of values generated y = sinc(x) plt.xlim(0, 25) # set range for x axis plt.ylim(-0.4, 1) # set range for y...

Hi there, I was wondering how computer programs such as geogebra or more advanced packages such as mathlab or wolfram plot graphs for functions. Do they calculate values and interpolate? Do they take derivates to determine maxima and turning points? Do they have any other way to somehow...

I've had Mathematica for years. I started having issues with it not too long ago. The first function I would plug in would work correctly, but then any command or function I'd plug in after that would do nothing. I had to literally restart Mathematica every single time I wanted to do the next...

Hi, I am not sure if I have solved the following task correctly I did the plotting in mathematica and got the following Would the plots be correct? What is meant by check for normalization, is the following meant? For the approximation for ##\epsilon > 0##, does it mean that for the...

This is basically a physics problem but I will try my best to highlight the mathematics behind it. Suppose I have two functions: $$T(z,B)=\frac{\text{z}^3 e^{-3 A(\text{z})-B^2 \text{z}^2}}{4 \pi \int_0^{\text{z}} \xi ^3 e^{-3 A(\xi )-B^2 \xi ^2} \, d\xi },$$ $$\phi(z,B)=\int_0^z...

Hello I'm trying to use FMESH command to get power distribution of this core geometry. I want to use xyz coordinate in a 1/12 slice of a core so I could use the output of the MCNP sim for a CFD input How should I approach this? Thank you

I expected this to be challenging but it's turning out to be much harder than I expected. I just flew back from Cuba to Toronto, got in at 315AM. It was a beautiful, clear and I had the window seat, so I took a bunch of pics. Now I'm plotting the flight path by analyzing the photos. It's super...

TL;DR Summary: Help needed with plotting heat maps, using data we gathered in an experiment. Hello, so I'm having problems with analysing data, which we gathered from an experiment we did in class. This is meant as a type of non-guided experiments class, where we are just given an initial...

I'm reading an article about the order-chaos-order sequence of a spring pendulum [Ref 1], as I'm reading it I'm trying to reproduce the graphs and results through Mathematica. However, I am new to this software. I will list below some of the most important equations mentioned in the paper. "In...

F.B.D Of first block (I have shown only the horizontal Forces) f1(max) = μ (1kg)(g) = 0.5 * 10 = 5N F.B.D Of the second Block f2(max) = μ (3kg)(g) = 15N Now the string will become taut and the tension will start acting when f = t = 5N But for 0<f<5N there will be no motion between the 1 kg...

Is it possible for Python matplotlib to plot in one graph a domain dependent function? For example, suppose there is a function where y=x from 0< x <=5, y = x sq when 5<x<=7 and y=2x+9 when x>7. Is it possible in Python to plot this with one plot on one graph? If so, how would it be done?

Can someone tell me how to plot/graph velocity in vpython? All the documentation I see just deals with plotting the position of the object, nothing on plotting the velocity.

Simply plugging this into software like MATLAB will present a solid guassian distrubution. However, my doubt comes from selecting the correct sigma. t = - 10 ns to + 10 ns ##\sigma## = 0.1 ns This produces a plot like so,

I'm designing a growth chart for my granddaughter with the planets on it. I wanted them to be proportional* as far as distance goes - with the sun at the floor and Pluto at, say, six feet, but obviously that's impossible since all the inner planets would be in the first inch or two from the...

Say I have phi starting at 0 and ending at 360 degrees. Theta starts at 0 and ends at 360, and I input 10 points for phi and theta. I am trying to 3d plot phi * theta number of points around a center point. I can plot a coordinate around a sphere using the following, which I think is correct...

I am trying to plot two functions a(t) and b(t) that both use a common intermediate result K. In my actual code K would be a slow-ish calculation. To reuse the K across a and b, I am putting them into a single module that provides an array {a, b} to the Plot[] function. (BTW, the Evaluate[] is...

Given the equation : ##|y| x = x##. Two conditions are possible : (1) ##\underline{y\geq 0}## : ##xy = x\Rightarrow \boxed{y = 1}\; (x \neq 0)##. We note that except for zero, ##-\infty<x<+\infty## for this case. (2) ##\underline{y < 0}## : ##-xy = x\Rightarrow \boxed{y = -1}\; (x \neq 0)##...
