Complex equation of a circle
WebAug 19, 2015 · The following formula is used to classify points from a 2-dimensional space: f (x1,x2) = np.sign (x1^2+x2^2-.6) All points are in space X = [-1,1] x [-1,1] with a uniform probability of picking each x. Now I would like to visualize the circle that equals: 0 = x1^2+x2^2-.6. The values of x1 should be on the x-axis and values of x2 on the y-axis. WebYou can set the expression equal to 0 making it an equation and then find its roots. Then take (x - first root)(x-second root) and that will be the factors of the original expression. While the method works for all equations. you sometimes get irrational factors and/or complex factors using the imaginary number.
