WebAnaxagoras in 450 BC is the first recored mathematician to study this problem. The problem of finding the area of a circle led to integration. For the circle with formula given above the area is \pi a^ {2} πa2 and the length of the curve is 2\pi a 2πa. The pedal of a circle is a cardioid if the pedal point is taken on the circumference and is ... Web⇒ (x – a)2 + (y – b)2 = a2 Expand this expression to get the required equation of the circle. ⇒ x2 + a2 – 2ax + y2 + b2 – 2by = a2 ⇒ x2 + y2 – 2ax – 2by + b2 = 0 It can be written as follows. ⇒ x2 + y2 – 2 (ax + by) + b2 = 0 This algebraic expression is the circle equation when the circle touches the y-axis in Cartesian coordinate system.
