4065UG-E-B 6/9/04 Çs 1:49 PM Page 23 Riser Limited — Used for situations when the riser height is limited by local code. When you press Ç s, the calculator will recalculate stair values so that the actual riser height will not exceed your stored desired riser height (e.g., it will never exceed the stored desired riser height of 7-1/2 inches, if 7-1/2 inches is the value stored using ß 7). To compensate for this limitation, the calculator will add one to the number of risers.
4065UG-E-B 6/9/04 1:49 PM Page 24 The Trig model (#4080) and Desktop (#44080) calculators have standard trigonometric keys, in addition to right triangle/rafter keys (e.g., rise, run, diagonal), for advanced right triangle mathematics. The sine, cosine and tangent of an angle are defined in relation to the sides of a right triangle. Using the Ç key with the trigonometric function displays the inverse (arcsine, arccosine, and arctangent).
