enter the coordinates of the point on the unit circle at the given angle. 90° (?, )
enter the coordinates of the point on the unit circle at the given angle. 90° (?, )
Answer
Explanation:
Step1: Recall the unit - circle coordinate formula
For a point ((x,y)) on the unit circle at an angle (\theta), (x = \cos\theta) and (y=\sin\theta).
Step2: Calculate (x) - coordinate
When (\theta = 90^{\circ}), (x=\cos(90^{\circ})). Since (\cos(90^{\circ}) = 0).
Step3: Calculate (y) - coordinate
When (\theta = 90^{\circ}), (y = \sin(90^{\circ})). Since (\sin(90^{\circ})=1).
Answer:
((0,1))
