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 (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 ………..

(sintheta-2sin^3theta)/(2cos^3theta-costheta) = …………….

(sin5theta+sin2theta-sintheta)/(cos5theta+2cos3theta+2cos^2theta+costheta) is equal to

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 sintheta-3sin2theta+sin3theta=costheta-3cos2theta+cos3theta , then one of the general value is:

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

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

if 13theta=pi ,then show that cos3theta+cos5theta+2costheta.cos9theta=0
