Formula Manipulation and Simplification

Simplify or modify expressions, substitute parts of expressions

Transform your expression into the particular form you require (expanded, factored, or expressed in particular terms) by choosing the appropriate function. See Choose Function to Rearrange Expression. If you just need a simpler expression, use simplify. You also can substitute for any part of an expression with another value by using subs.
