sin function in scientific calc

I'm . not sure if it's a huge error or I'm not using the calc correctly. but if you do sin(200.374) - type 200.374 and then hit "sin" - in apple's calc gives you as a result -0.348146686372052 when the correct result is -0.63493920883. Am I doing something wrong?

MacBook Pro (Retina, 15-inch, Mid 2014), macOS Sierra (10.12.4)

The Mac scientific calculator has a mode setting for Degrees/Radians in the lower left corner of its keypad.

Your "correct" answer is for 200.374 Radians shown in the display by a small Rad indicator.

The answer you cite as incorrect appears to be the result for Degrees, the default if no indicator is showing.
