Mathematica statements Clear

Mathematica has a powerful capability to carry out symbolic mathematics on algebraic expressions and can solve equations symbolically. In addition to the arithmetic operations, the principal Mathematica statements for manipulating algebraic expressions are Expand ], Factor ], Simplify ], Together ], and Apart ]. The Expand statement multiplies factors and powers out to give an expanded form of the expression. The following input and output illustrate this action In l] =Clear a,x]... 

The Clear statement is included in case a and x had been previously defined as variables with specific values, which would cause Mathematica to return a numerical result instead of a symbolic result. 

Mathematica can carry out indefinite integrals symbolically. For example, the input and output statements for the indefinite integral of sin(x) are In[l] =Clear[x]... 

Note the use of the blank space for multiplication. Note also that the Factor statement does not have its own input line number, because the Return key was pressed after the Clear statement, not the Enter key. The Simplify statement manipulates an expression into the form that is considered by the rules built into Mathematica to be the simplest form (with the fewest parts). This form might be the factored form or the expanded form, depending on the expression.
