" 10.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 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 tan theta , then find the value of (a^(2))/(x^(2))-(b^(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 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) ?

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

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

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

x=b sin^(2)theta & y=a cos^(2)theta

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