If line x cos ` alpha + y sin alpha = p " touches circle " x^(2) + y^(2) =2ax ` then p =

Find the value of p so that the straight line x cos alpha + y sin alpha - p may touch the circle x^(2) + y^(2)-2ax cos alpha - 2ay sin alpha = 0 .

The line x sin alpha - y cos alpha =a touches the circle x ^(2) +y ^(2) =a ^(2), then,

The line x sin alpha- ycos alpha = a touches the circle x^(2) +y^(2) =a^(2) ,then

The line x cos alpha+y sin alpha=p touches the circle x^(2)+y^(2)-2ax cos alpha-2ay sin alpha=0. then p=

Show that the equation of the circle described on the chord x cos alpha + y sin alpha = p of the circle x^(2) + y^(2) = a^(2) as diameter is x^(2) + y^(2) - a^(2) - 2p (x cos alpha + y sin alpha - p) = 0

If the line x cos alpha+y sin alpha=p and the circle x^(2)+y^(2)=a^(2) intersect at A and B then the equation of the circle on AB as diamerter is

If the line x cos alpha+y sin alpha=p and the circle x^(2)+y^(2)=a^(2) intersect at A and B then the equation of the circle on AB as diamerter is
