FullSimplify versus Simplify FullSimplify can handle expressions that Simplify leaves unchanged.

Here are more rules that FullSimplify knows about.
In[3]:=
|
Out[3]=

In[4]:=
|
Out[4]=
|
In[5]:=
|
Out[5]=
|
In[6]:=
|
Out[6]=
|
In[7]:=
|
Out[7]=
|
In[8]:=
|

|
In[9]:=
|
Out[9]=

In[10]:=

In[13]:=
|
Out[13]=
|
Differentiating a complicated indefinite integral should yield the integrand.
In[14]:=
|
Out[14]=
|
FullSimplify can handle the simplification.
In[15]:=
|
Out[15]=
|
The option ExcludedForms In the absence of any constraints, Factorial and Gamma cancel out in this expression.
In[16]:=
|
Out[16]=
|
Setting the option ExcludedForms to Factorial inhibits the simplification.
In[17]:=
|
Out[17]=
|
Setting it to Gamma does not, because Factorial is expressed in terms of Gamma.
In[18]:=
|
Out[18]=
|
In this example, partial simplification not involving Factorial is allowed to happen.
In[19]:=
|
Out[19]=
|
Here both the trigonometric functions and the gamma function are simplified.
In[20]:=
|
Out[20]=
|
By contrast, here the trigonometric functions are left untouched.
In[21]:=
|
Out[21]=
|
Using Assumptions This assumes that a, b, and c are positive (and so real by default).
In[22]:=
|
Out[22]=
|
This is a fairly complicated non-trivial example. The assumptions are that x, y, z, and n are integers, n is greater than  and x, y, and z are nonzero.
In[23]:=
|
Out[23]=
|
This simplifies an expression involving Fibonacci numbers.
In[24]:=
|
Out[24]=
|
This simplifies an expression involving Bessel functions.
In[25]:=
|
Out[25]=
|
