y = sin(xsin(ysinx)) (*zoom out*)

0 = x^3 + y^3 + 3xy , 0 = -x^3 + y^3 + 3xy , 0 = x^3 - y^3 + 3xy , 0 = x^3 + y^3 - 3xy (*These are four seperate functions that go together. They are manipulations of the Folium of Descartes.*)

1 = x^4 +y^4 (*A "Squircle"*)

1=\sqrt{x^{\cos y}}+\sqrt{y^{\sin x}} (*Creates an infinite grid of squircles*)

y=\frac{\left(\frac{x^{2}}{y}\right)}{\left|\left(\frac{x^{2}}{y^{2}}\right)\right|} (*A function that Desmos can't render. Makes staticky looking patterns everywhere*)

r=5\sin\left(\theta\right)+\cos8\left(\theta\right) (*Creates a clamshell*)

\cos\theta^{2}=0.001r (*Zoom out and click the home icon. "Warp speed!"*)

I have the word 'functions' crossed out because they aren't actually functions since they fail the vertical line test. I totally forgot about that little tidbit I learned in high school algerbra.
