  1. Let the circle with centre (a, b) be tangent to the y-axis. Then, the radius of the circle must be b. Therefore the equation of the circle is (x - a)2 + (y - b)2 = b2 or x2 - 2ax + a2 + y2 - 2by = 0 Then 2x - 2a + 2ydy/dx - 2bdy/dx = 0 ie x - a + ydy/dx - bdy/dx (y - b)dy/dx = a - x so dy/dx = (a -Read more

    Let the circle with centre (a, b) be tangent to the y-axis.

    Then, the radius of the circle must be b.

    Therefore the equation of the circle is

    (x – a)2 + (y – b)2 = b2

    or x2 – 2ax + a2 + y2 – 2by = 0

    Then 2x – 2a + 2ydy/dx – 2bdy/dx = 0

    ie x – a + ydy/dx – bdy/dx

    (y – b)dy/dx = a – x

    so dy/dx = (a – x)/(y – b) or -(x – a)/(y – b)
