http://en.wikipedia.org/wiki/Dot_product" is a Wikipedia about the Dot-Product, which includes the relevant section on Rotation. Given the first example- is it correct where it says "Notice that the rotation matrix R is assembled by using the rotated basis vectors u1, v1, w1 as its rows, and...

Thanks for the great answer, I understand now. Also- what exactly is the point of scaling the desired velocity vector to max speed? From what I can see- it will affect the direction as well as the magnitude of the output vector.

Homework Statement I'm having trouble understanding the physics equations related to Steering Behaviors For Autonomous Characters (present in the book "Programming Game AI by example"). For those that don't know- Seek is a kind of behavior whereby an object with a given mass, current...

Thank you :) So the fact that the current is entering a + or - of a voltage element has nothing to do with the repulsion or attraction of actual charges? I'll try say that in a slighty different way... The + and - terminals of such a voltage element are used only as convention... They...

Consider: ++++++++++ -> + [ELEMENT] - ++++++++ -> The way I see it- is that the force experienced by + charges as they approaches the + element is one of repulsion... which constitutes voltage pushing the charge in the opposite direction to the current? Same thing when it leaves the -...

I'm having a lot of difficulty understanding a really simple concept in my first year physics text. See the diagram below... http://www.avhq.com.au/~metrosexuality/ele_pass_conv.JPG "First, consider Figure 1.5-1a. When the current enters the circuit element at the + terminal of the...

A wave- like a sound wave traveling through the air? Aha! Beautiful! So... say, in copper- although the valence electrons can easily jump into the conduction band, they only ever really move small amounts in open space... because they soon collide with the nearby atoms (and their...

Wow, thanks for all the replies! I think I'm slowing catching on... I think I understand what you mean by the voltage being 'applied'. To make sure, I'm wondering what happens when an electron leaves the high potential side of a battery and enters the external copper wire? Does an...

I'm having a little difficulty understanding a few key electronic concepts and am hoping a some of you may be able to shed light. 1) In a power source (i.e. battery) I understand that E = V / D. Despite the size and mass of an electron being incredibly small; when enter the field- do they...
