Hi, I would like to ask a question on figure drawing. When communicating math/physics idea with other people, it is inevitable that formulas and figures are needed. For formulas we have TEX or Mathtype, but for drawing figures, is there very convenient tools that could quickly give...

I'm an engineer student, and I think I need a refresher on everything from algebra to calculus. Would definitely appreciate it if some of you can provide recommendations for some math self study software.

I have seen a lot of 3D software users of Modo, 3ds Max, Maya, etc that can produce a very nice looking product designs. These ranges of items made by them include car, building, machine, airplane, household electrical product, etc. They all look as good as the outcome produced by the CAD...

Firstly, I spoke to a Physics teacher and some strangers on the internet as well as Googled and this is the situation I am in now. I want to build a software simulation for school of a damped-oscillation non-zero charged metallic-sphere pendulum within the uniform electric field of a...

hello everyone, :smile: when i use my usb flash drive in some internet cafe or school lab it become infected. especially lab's computers are full of viruses. is there some software which i can have on my flash so that it protects flash from viruses. do you understand what i try to say? i want...

I've used Mathematica, and I find it really counter-intuitive. It's really complex for the user who isn't accustomed to math software, and doing simple mathematic functions, like addition/division/multiplication, etc. is insanely complex with Mathematica. Now, I know that a calculator is...

Hi all. Ok, so I'm a mathematics major, but I'm only so far as my first linear algebra course right now. I have not had any need to use Maple or Mathematica or Mathlab or a calculator for that matter. So, I'm curious WHEN I might have to start using these programs (what level math)...

Homework Statement So far, I've encountered two symbols on the GRE practice tests which are unknown to me. The first is a number in a square, like a telephone key The second is a number with upside-down "L's" next to it What do these mean?

Hi, I have a couple e-books, some in .pdf some in .djvu format. I'm trying to find a good program that ideally can use both formats and that is specifically designed for people who want to read on their computers. I just want to be able to add bookmarks and possibly make annotations, but with...

I am going to be redesigning some PCBs for some legacy products and want to use the most up to date software I can to keep these designs easy to update in the future. The current design is in Theda and the CAD files are no longer available. I appreciate any input.

It really frustrates me when I see my high school spending thousands of dollars every year on Antivirus software, Microsoft Office licenses, Microsoft Windows' keys, and other products such as Adobe Photoshop. As a heavy Windows and Linux user, I can safely say my experiences with both Operating...

To learn the process and check my work. Somthing like webmath. I'm looking for a software or website that allows you to enter known varialbes and it solves for unknown and shows you step by step how it did it. Anyone know of something like this? User friendly would be nice.

Having read previous threads going back to 2003, so far I am plummeting for Avast, but would like to ask members' opinion on this before I ask for Googles advice. Knowing I won't get a perfect fit, I need opinions on the best fit for the following criteria (in order): 1) Free 2) Gets...

Hi, Do anyone know where to get free process simulation software, please, if you know let me know, thanks.

i am a 3rd year civil engineering student, currently taking a course in which i need to use finite element software for assignments. the course is 100% theory, and i need to learn how to use the software on my own, i am looking for FREE software with FE capabilities, and preferably one that...

Hey I was wondering if anyone knew of a propeller design program, preferably written in Matlab, but I'd take anything. I am familiar with XFoil, XFLR5, and XPlane, but I don't know of any good propeller design programs. I have read into MPVL, but I'm pretty sure that is just designed for...

In all the Abaqus manuals I have read, it only tells me what the pre-tension option DOES, or a little bit about how it works, but what I want to know is literally which buttons to press to get to that option and how to apply it. I can't find the option anywhere in the software. Details of...

Hi guys, I need to test the airflow over a wing, I can't find any suitable software to do this job. I heard ANSYS is a good bet, but when I try I'm just lost... (not much exp with it). So anyone got any suggestions to analyse airflow of the wing.

I tend to think very independently, often coming up with unconventional, sometimes unorthodox, ways of solving problems. I do not like to listen to authority such as having to code up software a certain way or following strict guidelines/formats. Do you think the software...

So my friends try to explain it to me and everytime they do, i come to the conclusion that they're the same. I just don't understand. If somebody studies computer science, what do they learn? If somebody studies software engineer, what do they learn?

Hey guys, I'm looking for some software capable of allowing the user to input a specific mission profile and ultimately calculating empty weight and fuel weights providing input such as your L/D, cruise altitude, AR, Swet, Sref, ect. I'd even be interested in more advanced programs with the...

I'm an ME grad student and I'm in an upper-level dynamics class. It has become apparent that I'm going to want to use a symbolic solver. I'm familiar with MATLAB, but I hear that this is not MATLAB's forte. I also have MathCad, Maple, and Mathematica available to me. Which is the best for...

Hi A computer has some program written into its BIOS ROM which turns the hardware skeleton of a computer into a helpful machine. Is this possible to start a computer without that BIOS software using some circuitry. BIOS software is a firmware and I remember correctly I have read somewhere...

Hi guys this is my first post. I hope it's in the right place. I am trying to model heat flow over a plate positioned very close to exhaust from a jet engine. Can anyone recommend software that can do this? I'd like to be able to visualize the airflow itself, its temperature and the...

An excellent example of middleware would be a suite of software that helps serve an online gaming environment. More and more frequently, online games feature high-definition, high-resolution, graphic-intense presentations. Traditional server solutions are no longer enough to facilitate such...

I was wondering whether anyone knows of any downloadable or web-based applications that are geared toward theoretical and quantum mechanical physics equations. My IDEAL program would have: -The ability to solve and graph equations from quantum mechanics and theoretical physics (such as Loop...

Hi, I try to numerically solve the following partial differential equation for N(r,z) with a Dirichlet boundary condition. -\frac{\partial^2N}{\partial r^2}-\frac{\partial^2N}{\partial z^2} + f(r,z) \frac{\partial N}{\partial r} + g(r,z) \frac{\partial N}{\partial z} = h(r,z)...
