Hint:Use the equation for the unit circle (x^2+y^2=1) but this time, replace y with x.

**Reiny**, Wednesday, October 28, 2009 at 11:27pmso you would get

x^2 + x^2 = 1

2x^2 = 1

x^2 = 1/2 or

x = 1/±√2 or √2/2 after rationalized

then y = √2/2

so the two points would be

(√2/2,√2/2) and (-√2/2,-√2/2)
