This is an excerpt from my math models textbook. It's about Lagrange Polynomials which is a technique that lets you fit a polynomial to a set of any number of unique points (x_1,y_1) ... (x_n,y_n) so long as all your x-values are different (otherwise it wouldn't be a function, and couldn't be a polynomial). The polynomial you'll calculate will be the unique, lowest degree polynomial that passes through all points.

E[S] = μE[N]

Semi-related fun fact: The center of a KitKat is partly made of crushed off-cuts of the previous batch of KitKats. Which begs the question… what was the first KitKat made of?

was reading about cardoids when I was suggested mathematical deltoids.

image has two sides, left and right.
left being an image of a deltoid curve and right a deltoid muscle.

saw this comment on veritasium's latest video titled the SAT question everyone got wrong.

it's a nice video regarding rotation and revolution.

a comment below the aforementioned video by @arielrglaze reads , "It's messed up how messed up math has made us ignore what's obvious to the naked eye. it's even more messed up that we can't trust our eyes with anything."

Can you tell me why?

The volume of a cylinder is found using the formula V = πr^2^h. Using π = 5, r = 10 and h = 10. Find the volume V.
