Maths Example with Mathjax

Below is an example of maths using mathjax.

Any page needing maths should start with the frontmatter:

usemathjax: true

\begin{aligned} y = y (x, t) & = A e^{i θ} \\ = A (\cos θ + i \sin θ) \\ = A (\cos (k x - ω t) + i \sin (k x - ω t)) \\ = A \cos (k x - ω t) + i A \sin (k x - ω t) \\ = A \cos (\frac{2 π}{λ} x - \frac{2 π v}{λ} t) + i A \sin (\frac{2 π}{λ} x - \frac{2 π v}{λ} t) \\ = A \cos \frac{2 π}{λ} (x - v t) + i A \sin \frac{2 π}{λ} (x - v t) \end{aligned}

Inline maths can be written with the \$ and \$ characters, producing inline maths such as $δ (t) \overset{F}{\to} 1$ .

The above is accomplished with thanks to Alan Duan and Zichen Vincent Zhang.
