What's the general rule for constructing such graphs? I mean actually drawing it on paper.

1. The problem statement Is the magnetic field around the following two bar magnets: |N S| + |S N| the same as the magnetic field around: |S N| + |N S|? 2. The attempt at a solution Yes, but the arrows on the lines move in opposite directions?

Are there any good programs for drawing geometrical pictures? I mean that has functions for let's say creating circumcircles, marking centroids/circumcentres/Feuerbachpoints etc

Hi! I'm writing some lecture notes and I need to draw some complex integration contours. Is there any software to make this task easier? Thanks for your attention!

what is the most convenient Feynman diagram drawing tool? I have only grasped the method drawing feynman diagrams by usual Tex command as drawing other diagrams. For example "\ArrowLine(40.0,150.0)(90.0,150.0) ". But is very clumsy. Do you know other convenient Feyman drawing tool? I hear that...

Can someone discuss the physics behind pulling air into a syringe, inserting needle into med vial, expelling the air, and finally drawing up medication. This process makes it easier to draw up the liquid med as opposed to simply inserting needing and drawing up med. Thank you.

Homework Statement How do you draw a bode plot? I have a simple equation: H(S)=s+10 but no school book. Can you help me understand?

Hello Everyone, I'm a new user to both PF & Maxwell 3D. I've been having a lot of problems trying to draw a helical coil in Maxwell 3D v11. There is a 'CreateHelix' function in Maxwell 3D & when I use this function (which has to be drawn on a 2D object), I get this error: [error] Body...

What is a half decent schematic drawing s/w suitable for posting on PF? --and costs nothing? :smile:

I am having some issues with trying to figure out how to go about solving this problem. You have a standard deck of 52 cards and you draw 10 without replacement. What is the probability of drawing four of the same rank? (ex. 4 aces) Order doesn't matter, so I am thinking I have to do some...

I have an annoying problem. I have a paper to submit to a physics journal which requires that the figures be in eps format. The problem is that I am generating the figure I need using LaTeX commands (using a certain package for drawing quantum algorithms). The figure comes out exactly as I want...

1. What are the steps that I should take in drawing a plane for example if the equation is given of a plane x=y in 3 space what will the plane look like... what should I do in terms of steps? if i say x = 0 so does y and z can be anything with this information i can't...

I am fairly new here, There are lots of time I would like to scan a drawing or notes to put into the post, I can't find a good way. If I attach a file, it takes a day for moderator to clear it. The other choice is to put it online. I have seen people just put a jpeg file onto the post. Where can...

Hi all. I've searched the WWW, and it doesn't seem that there is an easy way of doing this. Do you have any experience with this? Thanks in advance. Niles.

Just for fun, thought I’d throw this out for discussion. What do you think is the best way to call out an SAE straight thread port on a drawing? For example, you could call out all the individual dimensions so that every machine shop would be able to machine it even if they’re not familiar...

Draw a graphic of the function using the basic elementary functions. For example. Draw f(x)=\frac{1}{x-1}-1. I know that I will first draw the function 1/x (basic function) then shift the graph of the function 1/x for 1 on right of the x-axis, so I got the graph of the function 1/(x-1). Then...

This is a problem for school that I need a little help with: Draw a circuit diagram that includes an electric motor, a green light, a red light, and a switch. If the motor is on, the red light should be on. If the motor is off, the green light should be on. Here is what I have so far. I'm...

The lit part of the moon in the dark sky is white, of course. What do you do when teaching on a whiteboard? If I use a blackboard, shading (with white chalk) the part that is lit make sense. However, I am always teaching on a whiteboard and using white paper in class. Therefore, I shade...
