    Curve Shape
AI Thread Summary
The discussion revolves around classifying the shape of a generated curve that exhibits exponential growth and decay characteristics. The curve is described as resembling a step response followed by exponential decay toward a saturation level, with specific time and amplitude attributes noted. Observations include a characteristic time of approximately 0.1 horizontal units and a final saturation value around 23 vertical units. Additionally, the presence of noise with an amplitude of about 2 vertical units is acknowledged. The conversation highlights the need for precise terminology to describe complex curve shapes in data analysis.

I have generated the graph shown below and now would like to describe it at a high-level according to the curved nature of the plotted line. Besides simply stating observations such as the exponential growth at approximately x = 0.19, is there a classification or term for the shape of the curve this line makes? Thank you.

semi-sinusoidal about an apparently exponential decay?

EDIT: also, "jagged" works for me :)

Hi ATroelstein!

It looks like a step response followed by an exponential decay to some kind of saturation level.
Looks as if the exponential decay has a characteristic time of about 0.1 horizontal unit and a final saturation value of about 23 vertical units.
There appears to be a noise level on top of that with an amplitude of about 2 vertical units.

Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
Is it possible to arrange six pencils such that each one touches the other five? If so, how? This is an adaption of a Martin Gardner puzzle only I changed it from cigarettes to pencils and left out the clues because PF folks don’t need clues. From the book “My Best Mathematical and Logic Puzzles”. Dover, 1994.
