 Usage
Notes
 Further Examples
Built-in transformation functions together with RootReduce are used to simplify this expression.
In[1]:=
|
In[2]:=
|
Out[2]=
|
The function ff gets rid of coefficients that are manifestly numbers.
In[3]:=
|
In[4]:=
|
Here Simplify uses only ff and no other functions to transform e2.
In[5]:=
|
In[6]:=
|
Out[6]=
|
Using NumericQ instead of NumberQ will also get rid of symbolic constants like  .
In[7]:=
|
In[8]:=
|
In[9]:=
|
Out[9]=
|
Here is a number.
In[10]:=
|
FullSimplify is unable to simplify e3.
In[11]:=
|
Out[11]=
|
Using the transformation function hh shows that e3 is equal to  .
In[12]:=
|
In[13]:=
|
In[14]:=
|
Out[14]=
|
Here is another number that FullSimplify cannot simplify to  .
In[15]:=
|
Builtin transformation functions together with the function kk show that e4 is equal to  .
In[16]:=
|
In[17]:=
|
Out[17]=
|
This number likewise reduces to 0 with the help of kk.
In[18]:=
|
Out[18]=
|
Here is another number that FullSimplify is unable to simplify to  .
In[19]:=
|
Simplify quickly returns  using the transformation function rr.
In[20]:=
|
In[21]:=
|
In[22]:=
|
Out[22]=
|
The following implies that the use of rr is legitimate in this case.
In[23]:=
|
Out[23]=
|
In[24]:=
|
Out[24]=
|
Let us verify that  . Sometimes it is easier for FullSimplify to show that two expressions are equal by showing that their difference is 0. This first attempt does not work.
In[25]:=
|
In[26]:=
|
Out[26]=
|
Built-in transformation functions together with mm show that e6 is equal to  .
In[27]:=
|
In[28]:=
|
Out[28]=
|
The use of mm is legitimate since n is an integer.
In[29]:=
|
Out[29]=
|
In[30]:=
