The straight line x cos theta+y sin theta=2 will touch the circle x^(2)+y^(2)-2x=0 if theta=n pi,n in IQ(b)A=(2n+1)pi,n in Itheta=2n pi,n in I(d) none of these

Find the condition that the straight line x cos theta+ y sin theta =p may touch the parabola y^(2)= 4ax .

The line x + y tna theta = cos theta touches the circle x ^(2) + y ^(2) = 4 for

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

The line (x-1) cos theta + (y-1) sin theta =1, for all values of theta touches the circle

If x sin^(3) theta + y cos^(3) theta = sin theta cos theta and x sin theta = y cos theta , then the value of x^(2) + y^(2) is :

If x sin^(3) theta + y cos^(3) theta = sin theta cos theta ne 0 and x sin theta - y cos theta = 0 , then value of (x^(2) + y^(2)) is :
