special symbols
Example 2:
 ≃ 3.14159
For this example we will suppose that:
• We want to enter the above formula (the value of pi rounded to 5 decimal
places).
• We know the name of the Greek character (pi).
• But we do not know the markup associated with the
≃
symbol.
Step 1: Type % followed by the text pi. This displays the Greek character

.
Step 2: Open the Elements window (View > Elements).
Step 3: The
≃
symbol is a relation, so we click on the Relations button. If you hover
the mouse over this button you see the tooltip Relations (Figure 8).
Figure 9 shows the Selection window after clicking the Relations button. The symbol
we want is circled.
