Rules Without Rulers
Custoslibera, I have never used a Cartesian plane in my life except for maths class.
Distinctly remember thinking I will never use this as well as I learnt it.
rambling_lunatic, Anyone in literally any STEM field regularly uses these bad boys.
somegeek, I’m not a math guru but there are only 4 shapes in this and there are 5 functions? You can describe a circle with a single function. Someone explain?
reverendsteveii, A graph is just a series of correlated points, a formula to tell you that when x is set to a certain value y has a different value. It follows then that no single function can define a circle because for every given value of x there would have to be two potential values of y.
akariii, f and g form the top an bottom of the circle. note that they only differ by a single sign
you need two of them because a circle can’t be expressed by a single function of x as it needs to map every x value to 0 to 2 y values
Chrobin, Well, you can describe a circle with a single function if you look at a function R -> R^2. But a circle can’t be the graph of a single function.
metaStatic, is tHaT a bAnKsEy???
bstix, Math checks out.
troglodytis, It was an anarchist match
