If `9x/costheta+5y/sintheta=56` and `9xsintheta/cos^2theta-5ycostheta/sin^2theta=0` then value of `[(9x)^(2/3)+(5y)^(2/3)]^3/784` is

If 9(x)/(cos theta)+5(y)/(sin theta)=56 and 9x(sin theta)/(cos^(2)theta)-5y(cos theta)/(sin^(2)theta)=0 then value of ([(9x)^((2)/(3))+(5y)^((2)/(3))]^(3))/(784) is

If (9a)/(costheta)+(5b)/(sintheta)=56 and (9asintheta)/(cos^(2)theta)-(5bcostheta)/(sin^(2)theta)=0 If the value of [(9a)^(2/3)+(5b)^(2/3)]^(3)=(8K)^(2) Then K is ………..

If x sin^(3) theta + y cos^(3) theta = sin theta cos theta ne 0 and x sin theta - y cos theta = 0 , then value of (x^(2) + y^(2)) is :

If cos3theta + sin3theta+(2sin2theta-3)(sintheta-costheta) lt 0 , then subset of value of theta is

If xsintheta+ycostheta=sintheta.costheta and xsintheta-ycostheta=0 find x^(2)+y^(2)

If sqrt3costheta=sintheta , then the value of (4sin^(2)theta-5costheta)/(3costheta+1) is:

If x sin^(3)theta+y cos^(3)theta=sin theta cos theta and x sin theta=y cos theta Find the value of x^(2)+y^(2)

(sin3theta+sin5theta+sin7theta+sin9theta)/(cos3theta+cos5theta+cos7theta+cos9theta)=?

If 3costheta=5sintheta , then ((5sintheta-2sec^(3)theta+2costheta)/(5sintheta+2sec^(3)theta-2costheta))=?
