Rat[(1+x)^ + 1]
did work.
How can I find out what commands have already been implemented?
For instance, the function N[\cdot] does not seem to work. Also,
floating point numbers can't be handled (or I don't know how to do it).
In[30] := Log[2]
OUT[30] = 0.69314718055994529
In[31] := Log[2 + 1/100]
OUT[31] = 0.69813472207098426
In[32] := Log[2.1]
OUT[32] = LOG[2.1/10]
In[33] := N[2.1]
OUT[33] = N[2.1/10]
In[34] := 2 + 1/10;
In[35] := 2.1;
In[36] := 2 + 0.1
OUT[36] = 2 + 0.1/10
In[37] := Log[%]
OUT[37] = LOG[2 + 0.1/10]
In[38] := 2 + 1/10;
In[39] := x=2
OUT[39] = SET[X, 2]
In[40] := y=1/10
OUT[40] = SET[Y, 1/10]
In[41] := Log[x+y]
OUT[41] = LOG[X + Y]
In[42] := Log[21/10]
OUT[42] = 0.74193734472937733
In[43] := N[%,30]
OUT[43] = N[0.74193734472937733, 30]
