If `x=a sin theta and y = b cos theta , " write the value of " (b^(2)x^(2)+a^(2)y^(2)).`

If x=a sin theta and y=b cos theta, what is the value of b^(2)x^(2)+a^(2)y^(2)?

If x = a cos theta ,y = b sin theta , then find the value of b^(2) x^(2) + a^(2) y^(2) - a^(2) b^(2) .

If x=a sin theta and y=b tan theta , then find the value of (a^(2))/(x^(2))-(b^(2))/(y^(2))

If x=a sin theta and y=b cos theta , then prove : (x^(2))/(a^(2))+(y^(2))/(b^(2))=1

If x=a sin theta and y=b tan theta , then prove that (a^(2))/(x^(2))-(b^(2))/(y^(2))=1 .

If x= 2sin^(2)theta and y= 2cos^(2)theta+ 1 then the value of x+ y is

If x=a cos theta - b sin theta , and y=a sin theta+b cos theta , what is the value of (x^2+y^2)/(a^2+b^2) ?

x=a cos theta,y=b sin theta, then findthevalueofb^(2)x^(2)+a^(2)y^(2)-a^(2)b^(2)
