Here is some useful information that I’ve created about the basics of trigonometry as well as the graphs. Part 2 is out. You can find it here.

All graphs come from Wolfram Alpha (very cool resource).

there’s an incredibly homophobic and transphobic page on facebook called heterosexuals inspiring pride and they make awful clip art comics that literally make no sense and im laughing so hard

as a certified Gay i can confirm that all of these are 100% correct

Weird and Gross Cis-Het Culture

I don’t… I… what…

It’s like they think men and women are actually cucumbers and vinegar. Breaking news! They’re not

seriously I’m struggling to see how this shit is actually real, jesus

Curves of Constant Width and Odd-Sided Reuleaux Polygons

A curve of constant width is a convex, two-dimensional shape that, when rotated inside a square, always makes contact with all four sides.

A circle is the most obvious (but somewhat trivial) example. Some non-trivial examples are the odd-sided Reuleaux polygons — the first four of which are shown above.

Since they don’t have fixed axes of rotation, curves of constant width (except the circle) have few practical applications. One notable use of the Reuleaux triangle, though, is in drilling holes in the shape of a slightly rounded square (watch one of the triangle’s vertices and notice the shape it traces out as it spins).

On a less technical note, all curves of constant width are solutions to the brainteaser, “Other than a circle, what shape can you make a manhole cover such that it can’t fall through the hole it covers?”
