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