wah......yes, you are correct.....do I need to go sit in the corner....years of college down the drain....

[MicHughV]

although .....wait....a perfect circle can have a tangent line go both ways from a particular point.......but yes, the example is not a perfect circle...never thought I'd have to do math here on the cruising forum...

ok, I give up....

Only closed curves have perimeters. That is not apparently a closed curve. It may be if it has enough parameters (To quote an aphorism attributed to John von Neumann "With four parameters I can fit an elephant, and with five I can make him wiggle his trunk”.


That's not different curves joined together. It's one curve.


And it's certainly not a "radiused arc" since an arc is part of a circle - and that's no circle.

Any tangent to any curve goes "both ways" from its "particular point".

Tangents are lines, and lines don't have directions.

They don't go one way or the other way or both ways. They just are.

They're lines, not vectors.

That said, what do you get when you cross a mosquito and a mountain climber?

A tangent to a "linear curve" is the same as the curve itself (linear means of the form ax+y i.e. a straight line).

Why is the line on the curve not tangent to the curve ?

This is The Joke Thread and you five have managed to go 14 posts having a discussion/argument about the mathematics in one joke. You are all humor impaired aren't you?

Ooooh, that was close. My therapy is coming along well.

I am so, so very sorry I started all that.

Things just got off on a little tangent, consider lightening up.

That was what was behind my original question, One can only assume that GI Low meant it was not a tangent when he said "I will not correct an inaccurate maths joke"



As far as I can tell, given the size of the original image, it is a tangent.

I am mocking them. At this moment I am taking humor from that.

Yep! But we also enjoy esoteric discussions that occasionally drift for a while from the main thread purpose. That's the nature of threads. You see it here frequently

So what's the inaccuracy?
