- 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)
yieldsa 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))))
yieldssqrt(x - 1) + 1
- Note: See also Factor Command, Assume Command, PartialFractions Command, Expand Command, Polynomial Command.
