Question about Texas Instruments TI-83 Plus Calculator
You have the calculator set up to do radians instead of degrees. I'm not that familiar with the TI-83 but I believe you should look for a key labeled DRG. This stands for Degrees, Radians, and, Grads. Push this key and then use the arrow keys to move from RAD to DEG and hit enter. Now enter Sin(30) and you should get 0.5.
