Multiple Lines in Equations
Multiple lines in equations are handled between the delimiters \ begin{align} and \ end{align} with each line separated from the next with the use of '\\' at the end. Each line can be aligned at a location designated by '&' on each line.
For example, that the equation: \begin{align} & \text{if}\quad r\le 1.57\quad {{f}_{w}}=0.3 \\ & \text{if}\quad r>1.57\quad {{f}_{w}}=0.00251\ \exp \left( 5.21\ {{r}^{-0.19}} \right) \\ \end{align}
was typed as follows:
\ begin{align}
& \text{if}\quad r\le 1.57\quad {{f}_{w}}=0.3 \\
& \text{if}\quad r>1.57\quad {{f}_{w}}=0.00251\ \exp \left( 5.21\ {{r}^{-0.19}} \right) \\
\ end{align}
