[" (ii) If "2y cos theta=x sin thetaquad " and "2x sec theta-y cosec theta=3],[" show that "x^(2)+4y^(2)=4]

If 2ycos theta =x sin theta and 2xsec theta-ycosec theta =3 show that x^2+4y^2=4

If 2y cos theta= xsin theta and 2x sec theta-y cosec theta=3 then x^2/4+y^2=

If 2y cos theta =x sin theta and 2x sec theta -y cosec theta =3, then x ^(2) +4y^(2)=

If 2y cos theta =x sin theta and 2x sec theta -y cosec theta =3, then x ^(2) +4y^(2)= ............... A) 4 B) -4 C) -2 D) 2

If x= cosec theta -sin theta and y=sec theta-cos theta, then show that x^(2//3)+y^(2//3)=(xy)^(-2//3)

If 2ycos theta =x sin theta and 2x sectheta -y "cosec"theta =3 , then the relation between x and y is:

If x=cosec theta-sin theta and y=sec theta-cos theta then prove that x^(2/3)+y^(2/3)=(xy)^(-2/3)

If xsin^(3) theta +y cos^(3) theta=sin theta cos theta and x sin theta =y cos theta , then prove that x^(2)+y^(2)=1 .
