y=+- square root 5 over 3 y=+- square root 7 over 3 y=+- 3 over 3
y=+- 2 square root 2 over 2
Equation of unit circle is: x² + y² = 1 we plug in the values of y to get the values of x. x² +√(5/3)² =1 x²=1- (5/3) x²= -2/3 x=√(-2/3) solve the rest by using the same technique and solve each value of y for x
