Show, using implicit differentiation, that any tangent line at a point P to a circle with center O is perpendicular to the radius OP. If the circle has radius r, its equation is x2 + y2 = r2 ⇒ + 2yy' = 0 ⇒ y' = , so the slope of the tangent line at P(x0, y0) is . The negative reciprocal of that slope is , which is the slope of OP, so the tangent line at P is perpendicular to the radius OP.
