Misc. Graphing Calculator FAQ's

Question: I have a graphing calculator. How do I print out its screen?

Answer: The ECA 225 lab has the graph link software installed. Students can use the lab from Mo-Th 7-10:00pm Sa/Su noon-4:00pm this
semester. Students will need to bring their calculator and graph link cable.

Question: I have a TI-86. When I enter arcsin(2) it gives me a complex number answer. Is there any way to turn this feature off?

Answer: No. If you entered arcsin(2) on your old TI-83 it would give a domain error. On the newer calculators this has changed.
