Simplify Command

Simplify( <Function> )

Simplifies the terms of the given function, if possible.

Simplify(x + x + x) yields the function f(x) = 3x.

Simplify( <Text> )

Attempts to tidy up text expressions by removing repeated negatives etc.

For a = b = c = -1 Simplify("f(x) = " + a + "x² + " + b + "x + " + c) yields the text f(x) = -x2 - x - 1.

The FormulaText Command normally produces better results and is simpler.

This command needs to load the Computer Algebra System, so can be slow on some computers. Try using the Polynomial Command instead.

CAS Syntax

Simplify( <Function> )

Simplifies the terms of the given function, if possible. Undefined variables can be included in the terms.

Examples:

  • Simplify(3 * x + 4 * x + a * x) yields a x + 7x.

  • Assume(x<2,Simplify(sqrt(x-2sqrt(x-1)))) yields -sqrt(abs(x - 1)) + 1

  • Assume(x>2,Simplify(sqrt(x-2sqrt(x-1)))) yields sqrt(x - 1) + 1
