Q:
Sarah used her calculator to find sin 125°. She wrote down sin 125° = -.57. How could Sarah recognize that her answer is incorrect?
Accepted Solution
A:
sin125, on the unit circle, should be positive(not negative), since it should be in quadrant two if the angle 125 degrees is in standard position.
