WebTranscribed Image Text: Step 3 Hence, VF(x, y, z) = -2xi + (-2y + 7)j - k. If F is differentiable at(x, y, z) and VF(x, y, z) = 0, then VF(x, y, z) is normal For any points at which the tangent plane is horizontal, the gradient vectorVF(x, y, z) is parallel to the Step 4 Therefore, VF will contain only a Hence, the coefficients of i and j in the equation for VF will be equal to 0. WebJul 18, 2024 · Given equation of circle: x2 + y2 −2x −6y + 6 = 0 can re-written as (x −1)2 + (y −3)2 = 4 The above circle has center at (1,3) & radius 2 Let tangent passing through the point ( −1,2) be drawn at the point (h,k) on the circle: x2 + y2 −2x −6y + 6 = 0 then the point (h,k) will satisfy the equation of circle as follows
