###### Monte Carlo approximation of the area of heart

Problem A popular mathematical equation for 2D heart is the following, $f(x,y) = (x^2 + y^2 - 1)^3 - x^2 y^3 = 0$ Any $(x,y)$ values that result in $f(x,y) < 0$ represent the coordinates of a point that falls...

###### Logic NAND equivalence

We have learned that, $\begin{eqnarray} \bar{A} &=& A \uparrow A ~, \nonumber \\ AB &=& (A \uparrow B) \uparrow (A \uparrow B) ~, \nonumber \\ A + B &=& (A \uparrow A) \uparrow (B \uparrow B) ~, \nonumber \end{eqnarray}$ Now,...
