[" If "P_(1)" and "P_(2)" be perpendicular from the oric "],[x sec theta+y cos ec theta=a" and "x cos theta-y sin],[" then the value of "4P_(1)^(2)+P_(2)^(2)" is "]

If p_(1) and p_(2) are the lengths of the perpendicular form the orgin to the line x sec theta+y cosec theta=a and xcostheta-y sin theta=a cos 2 theta respectively then prove that 4p_(1)^(2)+p_(2)^(2)=a^(2)

If p and p' be perpendiculars from the origin upon the straight lines x sec theta+y"cosec"theta=a and x cos theta-y sin theta=a cos 2theta , then the value of the expression 4p^(2)+p'^(2) is :

If p_(1)andp_(2) are respectively length of perpendiculars from the origin to the straight lines x"sec"theta+y"cosec"theta=a " " and x "cos"theta-y"sin"theta=a"cos"2theta , then 4p_(1)^(2)+p_(2)^(2) is equal to

P_1 and P_2 are the length of perpendicular from origin to the line x sec theta + y cosec theta =a and x cos theta - y sin theta = a cos 2 theta then ….... of the following is valid.

If x = sin theta and y = cos p theta , p is constant, then find the value of (1-x^2) y_2 - xy_1

If p and q are the perpendicular distances from the origin to the straight lines x sec theta - y cosec theta = a and x cos theta + y sin theta = a cos 2 theta , then
