The equation of the tangent in the form y mx c The coordinates of the centre of the circle are ab 4-5. A collection of circles is called as a system or family of circles. Polar equation of a circle with a center at the pole Polar coordinate system The polar coordinate system is a two-dimensional coordinate system in which each point P on a plane is determined by the length of its position vector r and the angle q between it and the positive direction of the x.
I know the equation for a circle in general form is texx2y2r2 tex First I found the distance between the two points given because this also equals the diameter. The number being subtracted from the x in the brackets is the x-coordinate of the center. The equation of diameter is x 0 y 0 1 0 3 0.
