Question

Determine the corresponding ordered pair of the point on the unit circle for 945° ​

Answer 1

Answer:

The trick is to turn the 945 degrees angle into a manageable angle

945/360 = 2.625 we have an angle equal to 945-720 = 225 degrees, this is an angle located in the third quadrant with the functions of 45 degrees but sin is negative and cosine is negative etc.

The point has the coordinates ((-√2/2),(-√2/2))
