The point P is on the unit circle. Find P(x, y) from the given information.

Question

the y-coordinate of p is 3/4, and the x-coord. is negative

p(x,y)= ( )

Answer 1

(3/4)^2 + x^2 = 1^2

x^2 = 1 - 9/16 = 7/16

x = - (sqr7)/4 = about - 0.661

the points approximately (-0.661, 0.75) and ( -0.661, 0.75)
