### Notation systems

Some Math Insight pages allow readers to choose notation systems, These notation systems customize the expression for some mathematical objects, such as line integral or surface integrals, to match that of a textbook. On those pages with multiple notation systems available, a box to select the notation system appears at the right.

The following notation systems are defined:

• default: Math Insight default notation
• Marsden and Tromba: Notation used by Marsden and Tromba, Vector Calculus (currently same as default)
• Stewart: Notation used in Stewart calculus
