Question about Texas Instruments TI-84 Plus Calculator
Having graphed a Sin function and a straight line simultaneously, I wanted to find the Y-value at X = 1 of the Sin function. So, naturally I hit [2nd] [CALC] and executed the Value function, having X = 1. However, when I hit [ENTER], the calculator froze completely and all keys became unresponsive.
The problem persists even when the four batteries are removed, replaced and the calculator is turned back on; all keys still remain completely unresponsive.
When four *new* batteries were used, the calculator resumed normal functionality. However, again, when the Value function on the same pair of graphs was used, the calculator again froze, turning all keys unresponsive yet again.
Any assistance with this problem would be greatly appreciated.
