everyone in class had a TI graphing calculator. In some ways this was better than a cell phone: If you wanted to play BlockDude instead of doing trig identities, this was much more discrete.

Scientific calculators were invaluable to most of us through high school and college, freeing us from the yoke of using tables to calculate logarithms and trigonometric functions. Once out in the ...

The graphs of \(y = \sin{\theta}\) and \(y = \cos{\theta}\) can be plotted. The graph of \(y = \sin{\theta}\) has a maximum value of 1 and a minimum value of -1. The graph has a period of 360°.
