# Nicomachus's Theorem/Proof 1
## Theorem
$\ds 1^3$ $=$ $\ds 1$ $\ds 2^3$ $=$ $\ds 3 + 5$ $\ds 3^3$ $=$ $\ds 7 + 9 + 11$ $\ds 4^3$ $=$ $\ds 13 + 15 + 17 + 19$ $\ds \vdots$ $\ds$
In general:
$\forall n \in \N_{>0}: n^3 = \paren {n^2 - n + 1} + \paren {n^2 - n + 3} + \dotsb + \paren {n^2 + n - 1}$
In particular, t... |
## How do you write the standard form of the equation of a circle?
The standard form of a circle’s equation is (x-h)² + (y-k)² = r² where (h,k) is the center and r is the radius. To convert an equation to standard form, you can always complete the square separately in x and y.
