Question

Identify the terminal point for a 45° angle in a unit circle.

Answer 1

Answer:

D

Step-by-step explanation:

x- coordinate = cos45° = $\frac{1}{\sqrt{2} }$ = $\frac{\sqrt{2} }{2}$

y- coordinate = sin45° = $\frac{1}{\sqrt{2} }$ = $\frac{\sqrt{2} }{2}$

That is ( $\frac{\sqrt{2} }{2}$ , $\frac{\sqrt{2} }{2}$ ) → D
