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 2ycos = xsin theta and 2 x sec theta -y cosec theta = 3 , then the value of x^2+ 4y^2 is यदि 2ycos = xsin theta and 2 x sec theta -y cosec theta = 3 हो, तो x^2+ 4y^2 का मान क्या होगा?

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

If x sin ^3 theta +y cos^3 theta = sin theta cos theta and x sin theta =y cos theta then x^2 +y^2 is

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