- Substitute( <Expression>, <from>, <to> )
- Substitutes from in expression with to.
- Examples:
Substitute((3 m - 3)^2 - (m + 3)^2, m, a)yields 8 a2 - 24 a.
- Substitute( <Expression>, <Substitution List> )
- Substitutes in expression every variable of the list with the variable or number you choose for it.
- Example:
Substitute(2x + 3y - z, {x = a, y = 2, z = b})yields 2a - b + 6.
