“In 1980, #Intel released the #Intel8087 #FloatingPoint coprocessor, a chip that could make math up to 100 times faster. As well as arithmetic and square roots, the 8087 computed #transcendental functions including #tangent, #exponentiation, and #logarithms.
But it all depended on a 69-bit adder: "The arithmetic heart of the floating-point execution unit is centered about a #nanomachine comprised of the adder and its related #registers, #shifters and control circuitry," as the patent describes it”

And so, here are four functions to demonstrate it. The default resolution of the plotting routine is crude, leading to #Aliasing and so the mesh has to be refined somewhat.
Here are three #ConicSections and one #Trigonometric functions.
An #Ellipse
A #Parabola.
A #Hyperbola.
A rotating #Tangent function.#MyWork #CCBYSA #Maxima #Mathematics #Geometry #FreeSoftware

I use #NextcloudNotes, #Zettlr, #kwrite and a bit #tangent ( and obsidian too, but :blobcatgooglytrash: )I try also orgmode with #orgzlyrevived and I like it - I tried also #emacs but that too hermetic for me … :blob_sweat:
