9 Math

If \(a^2=b\) and \( b=2 \), then the solution must be either \[ a=+\sqrt{2} \] or \[ a=-\sqrt{2} \]

LaTeX formatted equation: \[ E = -J \sum_{i=1}^N s_i s_{i+1} \]

9.1 latex fragment

\begin{equation} \Pr(X_t=j|X_{t-1}=i) = \frac{j(j-1)}{2}\Big(\frac{i}{N}\Big)^j\Big(\frac{N-i}{N}\Big)^{n-j} \end{equation}
