Backspace button

For technical reasons, your keyboard BACKSPACE button should not be used to correct errors made during data input. The default state of the input cells on all the calculator worksheets is that they contain the number zero. 

The function block on the top (Fig. 10.16) comprises the trigonometric functions sine, cosine, and tangent. Use the Backspace <— button to delete your last input. Click on Pi to enter the number n.
