  3. Enter the limiting variable in the placeholder to the left of the arrow below the "lim."
  4. Enter the limiting value in the placeholder to the right of the arrow below the "lim."
  5. Press [Spacebar] until the entire expression is between the editing lines.
  6. Press [Ctrl] [.] or click the right arrow on the Symbolic toolbar to insert the symbolic equal sign.
  7. Click outside the expression or press [Enter].

If the limit does not exist, Mathcad returns an error message.

Example:
