Question about Texas Instruments TI-84 Plus Calculator
Not quite sure whats going on...
Heres what happens
I hit the Sin button, enter in the degrees "sin(30)" for example. Instead of .5000, which is what the sine of 30 actually is, it comes up as -.9880316241
I cleared all my memory/ram etc and same problem.
The problem is that you have the mode in radians. You want them in degrees. This is a simple fix. Press mode and then go down to radians and select degrees
