Useful LaTeX

LaTeX notation can specify inline or display mode for maths by delimiting with \( or \[ respectively. Here are some simple examples:

• x^2 gives $x^2$
• x_n gives $x_n$
• x^{2x} gives $x^{2x}$
• \alpha\beta gives $\alpha\beta$
• \sin(3\pi x) gives $\sin(3\pi x)$
• \frac{1}{1-n^2} gives $\frac{1}{1-n^2}$ when inline. In display mode it gives:

$$\frac{1}{1-n^2}$$

• \int_a^b x^2\ dx gives $\int_a^b x^2\ dx$ when inline. In display mode it gives:

$$\int_a^b x^2\ dx$$
