Find the terminal point Px y on the unit circle determined b

Find the terminal point P(x, y) on the unit circle determined by the given value of t.

t = 3/2

P(x,y,)= (------)

Solution

x=cos t = cos(3/2) = -1

y =sin t = sin (3/2) =0

therefore the pterminal plot on the unit circle determined by t =3/2 is P(x,y) = (-1 , 0)
