Question about Texas Instruments TI-84 Plus Silver Edition Graphic Calculator
This is to use to solve a right triangle. When you're trying to find the missing angle. You use Sine, Cosine, and Tangent depending on which angle you're trying to find. But the buttons are weird.. and obviously it should be a positive number.. even though it turns out negative. Why is that?!!!
a 6ya Technician can help you resolve that issue over the phone in a minute or two.
