Calling Sequence

solve(eqn, fcnname)

Parameters

eqn

-

single equation (as for solve)

fcnname

-

single variable (as for solve)

Description

• 

When the unknown is a name which is only used as a function in the equation, the solver constructs a function or procedure which solves the equation.

Examples

solvefxx+2,f

x→x2

(1)

This is more or less equivalent to:

solvefxx+2,fx

x2

(2)

unapply,x

x→x2

(3)

This in turn is more or less equivalent to:

solveyx+2,y

x2

(4)

unapply,x

x→x2

(5)

More complicated inputs will generally return answers involving RootOfs

solvefx4fx3+x+1,f

x→RootOf_Z4_Z3+x+1

(6)
