solve/identity - solve expressions involving identities

Calling Sequence

solve(identity(eqn, x), vars)

Parameters

eqn

-

equation, or expression (equated to 0)

x

-

identity variable

vars

-

variables to be determined (as for solve)

Description

• 

The expression (or equation) eqn is considered an identity in terms of the variable x, and solve attempts to find a solution in terms of vars which satisfies the equation eqn for any value of x.

• 

This is a one-dimensional case of a generalized pattern matching.

• 

x should not be one of the vars.

Examples
