Question

Find the terminal point on the unit circle determined by 5pi/4 radians

Answer 1

The terminal point represented by P(x,y), is the coordinate where a certain point lies. Given is 5pi/4 radians - this will be our angle.

Evaluate the values of x and y using sin θ and cos θ

x = cos (5pi/4)
x = -√2/2

y = sin (5pi/4)
y = -√2/2

Therefore, (x,y) is (-√2/2, -√2/2)
