Display Common Trigonometric Values 

It is easy to create a table of values for any function.

Create a table of values of the basic trigonometric functions for multiples of .

In[1]:=

X values = Table[{Inactive[Sin][\[Theta]] == Sin[\[Theta]], Inactive[Cos][\[Theta]] == Cos[\[Theta]], Inactive[Tan][\[Theta]] == Tan[\[Theta]]}, {\[Theta], 0, 2 Pi, Pi/12}];

Each row contains the values of the three trigonometric functions.
