Here is a list of points.
In[1]:=
|
Here is a plot of points.
In[2]:=
|
This fits the data to a straight line with x intercept -2.
In[3]:=
|
Out[3]=
|
This plots the line.
In[4]:=
|
This shows the line together with points.
In[5]:=
|
Here is a table of the sum of the squares of the divisors of the first  positive integers.
In[6]:=
|
Out[6]=
|
Here is a plot of divisorsigma2table.
In[7]:=
|
Here are linear and quadratic fits to divisorsigma2table.
In[8]:=
|
Out[8]=
|
In[9]:=
|
Out[9]=
|
Here are the plots of the linear and quadratic fits.
In[10]:=
|
This shows the linear and quadratic fits superimposed on the original data. The quadratic fit is better than the linear one.
