perpar spigoli 90°

[todaniele]

Good morning to all,

using the trajpar function in the following form "sd4=10*sin(trajpar*360*10)" I get the attached figure.
to me it would serve that the sinusoid that develops along the given circumference, was not tuned but had the edges at 90°, as if it were a saw tooth (see red touch in the attached image).

Would you please give me a hand?

How does a sinusoid have the living edges?

How does a sinusoid have the living edges?

Neesuno is asserting that a synenoid "must" have the living edges, all was able to make the idea of what was to be the result in graphic and non-mathematic form.

p.s. I forgot to say that the question was discussed within a similar post within this forum.
