Graphic Definition and 55 Threads

Hi! My name is Jose and even though I'm not smart enough to be an engineer, but I've always enjoyed the design aspect of it (probably that's why I became a graphic designer). I also like to invent stuff in general. I am joining PF because it seemed like an honest and down-to-earth forum...

Hi guys! I have problems with this mechanism...finding the aceleration with graphic method. I already have drawn the speed diagram and the values of all of them. But, i dont know if my aceleration diagram it is well drawn. I'm stuck especially when trying to plot and calculate the...

Just stumbled over this one: https://readcomiconline.li/Comic/Marie-Curie-A-Quest-For-Light I know I'm one out of around only ~7 people who can stomach the amount of ads on these sites. It helps to set it to "low quality" and "show all pages" though. Anyway, the thing *can* be bought the old...

I am not sure, but since the partition function Z is just the sum of all Boltzmann Factor We can just add: (some terms don't appear in the image, by the way, the estimative is nice, the result is above ANS) But i didn't understand what the author did: While i didn't even care about the...

https://www.fmglobal.com/research-and-resources/tools-and-resources/resilienceindex/explore-the-data/? Below the world map, there is a horizontal graphic with dots corresponding to each country. The dots are broadly ranked from right to left according to a measure of "economic resilience", but...

On 2/7/17 the following explanation of an accompanying graphic on phys.org read as follows: "Integrated intensity distribution of CCH, superposed on the 0.8 mm dust continuum map. The infalling rotating envelope traced by CCH is broadened inward of the radius of about 150 au. Credit: Sakai et...

This has been bothering me for some time, and would like to get a physicist's view of it. If my understanding or contention is in error, please correct me (gently). I only have under grad physics from 1970, and was a microbiologist, though am interested in quantum physics, cosmology. My...

If a hypothetical planet was once where the asteroid belt is now, and was removed (for example exploded and fell inwards towards the sun where it got burnt up), would this cause the inner planets to migrate outwards into new orbits due to the orbital resonance lost by this hypothetical planet...

Homework Statement Graph the ellipse 4x² + 2y² = 1 Homework Equations 4x² + 2y² = 1 The Attempt at a Solution 2x² + y²/2 = 1/2 I searched for exercises on Google, and i didn't find an equation like that. I watched videoleassons too but it didn't teach this type of equation.

Hello, I am having trouble comprehending how grids are made and defined in computers. What is the unit that they use and how is it defined ? I know that softwares use standardized units of measure (measurement) such as centimetre. Basically, how is a 3-Dimensional Space created in computers...

Homework Statement Use a (simplified) graph to compare the maximum probability (electron density) of the Radial Distribution Function for the 1s and 2s orbitals. Homework Equations xxx The Attempt at a Solution The rest I don't how to solve.[/B]

Most software bugs are so obscure, that only the person who fixes the bug truly understands what went wrong and why. I love this video because it makes bugs marvelously visible. I can almost imagine the lines of incorrect code, or the unstated incorrect assumptions, or the failures to...

There is a relationship between each of the mathematical values in each of the paradoxes with regard to each observers. There is obviously also a relationship between every situation we study in the Special Theory of Relativity. The Lorentz Transformations obviously prove this. So, I began to...

Homework Statement So I have to make three charts for the measurments that we made in class (physics experiments but it's not important). The first one had to be with a linear trendline, the second one with a exponential and the third one with a logarithmic trendline. For some reason the last...

I have some data points that I want to plot and suppose I have the function ##f(x) = x##, with the domain having the range ##0\leq x \leq 10##. Assume that the experimental values lies in the range ##4\leq x \leq 7##, how can I put a rectangular region to cover this range behind my plot so as to...

Trying to complete some homework help I got a bit stuck on an elementary or common problem that was always a bit difficult. I have a function f(x) and just want to plot log f(x) against log x. This is common in chemistry and biochemistry. It should have been easy. :redface: I have picked up...

This is for a fictional project, but the tools I need will more likely be found here in Earth forum, I think. Move to fiction if necessary. I want to render a map of Earth with the "poles" of the grid in a different place. Say, the South "pole" of the grid is at Tierra del Fuego (ish) in S...

I want to write a program when I click the turtle, the turtle would disappear. However, the program does not gave error message but when I click the turtle, there is no effect on it. What's wrong with it? How can I fix it? Thanks Mod note: Added code tags. My written programme: import turtle...

I made some tweaks to the diagram you may have seen me post in threads about delayed erasure. Let me know what you think, what's confusing, etc. Here's the updated version: And the old version:

y = a x² + b x + c is a parabola. But, a parabola is just a kind of conic. All conics are given by a x² + b x y + c y² + d x + e y + f = 0 The same way, the graphic y = f(x), with f(x) satisfying a d²f/dx² + b df/dx + c f = 0, is just a particular graphic of F(x,y) = 0 with F(x,y) satisfying...

A recent article on Proton/Lead collisions (http://physics.aps.org/articles/v8/61) used a graphic seen in earlier articles on Proton/Proton collisions (ie. http://arxiv.org/pdf/1206.0148v1.pdf). I understand the gray disks to represent protons just after the collision (flattened due to...

Homework Statement How can I calculate the ultimate stress? (I refere to the stress that it's in the green rectangle). I have a real graphic, I have two deformations, (it was 2 test, from the same material) and only one stress. The orange curve is Stress versus unit deformation 1, and the gray...

I need to do this graph "graphic locking range and stability laser" that equations are used to make the graph thanks

Evening... I`m looking for some kind of graphics editing software, allowing to draw 3D sketches and view them through anaglyph glasses (blue-red). The main purpose is just to assist my imagination in solving 3D geometry problems, so I prefer it to be as simple as possible. It would be great...

Graphic Interpretation for Ʃf(x)Δx Hello! I was trying to understand what means: \sum_{x_0}^{x_1}f(x)\Delta x (when Δx = 1 and x ∈ Z, ie, a "discrete integration", topic very comun in discrete calculus). I computed the result so: \sum_{1}^{4}x^2\Delta x=\left...

Hello! We know how is a primitive of a any function (file 1), but how will be the graphic of a function like the at file 2 (is a descontinued function, periodic with a unit value in a point interval)?

Writing Sci-fiction Graphic Novel need advisement in "space travel" I've used VASIMR rockets as a reference and cited them as precursors to what now allows "rapid stellar travel" at say Earth to Mars in forty eight hours. Any advice on how this could be at least theoretically possible?

In the computer world at least, the symbol ^ is often used for exponentiation. I was just wondering if log has had anything in the multitude of languages out there. It would be nice to see an operator such as "1000¬10=3" instead of writing LogBase10(1000)=3 which is more ugly. I'm writing a...

First, my apologies ... my last math class back in high school, sophomore year geometry, many years ago. I am a graphic designer, but have discovered an interesting math problem and would like some help identifying what it is and how to better express and use it. Thanks for any help! And...

Matlab "clones" - Graphic interface? I am not into high level maths, but struggling with them from time to time when trying to solve some (for me) unusual problems. Is it any of the so called "Matlab clones" available with GUI? Command line is something that would add an extra concern to...
