Simplify Command

Simplify( <Function> )

Simplifies the terms of the given function, if possible.

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

Simplify( <Text> )

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

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

Note:

The FormulaText Command normally produces better results and is simpler.

Note:

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
