An involute of a circle can be obtained by rolling a line around the circle
- in a special way. -- CHECK
Involute is also known as evolvent.
- This is pretty obscure, at least I only see this in dictionaries, and not in common use. Maybe ditch it? -- CHECK
To Draw an Involute
- It would be great to have this so you could state a step, then click something to animate, etc. (This is done in one big glop in your next section). -- CHECK
This error gets smaller as we construct more tangent lines that they are near enough together.
- you don't way the "they" in that sentence. -- CHECK
Involute is also the roulette ...
- You want: The involute is also ... --CHECK
What's wrong with this sentence?
- He invented and built the world's first pendulum clock in 1956 --CHECK
More Mathematical Explanation
This property holds true for all other types of curves as well
- as we shall soon see. -- CHECK
Do we want Properties and Formulas under More Mathematical Explanation, or could they be just small subsections? (would this be allowed??) -- I think these two sections are actually more mathematical than the examples and I should hide them. I'll see what other people think about this.
I think the various examples of involutes should all be hidden with just their names showing. Similarly, just General Formula showing and derivation hidden. -- CHECK
From the present: please explain pitch-circle and base circle. Picture is nice but may not be quite enough. --CHECK
One of the most commonly used gearing system today is the involute gear.
- involute gear in boldface or italics --CHECK
Comments from the Past
Actually, Tanya, both Mathworld and Wikipedia have pretty accessible looking articles on involutes, so maybe we should link to them when needed.
I'm having issues on how to go about the involute. I will try to find some more about it in textbooks, but I am not sure if there is a tangent involved at all, or how the length of the line relates to the curve, etc. Any insight is welcome.
