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

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

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

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

If xsin^3theta+ycos^3theta=sinthetacostheta and xsintheta-ycostheta=0 ,show that x^2+y^2=1

if xsin^3theta+ycos^3theta =sin theta cos theta and x sin theta -y cos theta =0 prove that x^2+y^2=1
