Previous Year Question (PYQs)
If $x=a\cos^{2}\theta\sin\theta$ and $y=a\sin^{2}\theta\cos\theta$, then $(x^{2}+y^{2})^{3}$ is …
Solution
$x^{2}+y^{2}=a^{2}\sin^{2}\theta\cos^{2}\theta$. So $(x^{2}+y^{2})^{3}=a^{6}\sin^{6}\theta\cos^{6}\theta = a^{2}(a^{4}\sin^{6}\theta\cos^{6}\theta)=a^{2}x^{2}y^{2}$.Online Test Series, Information About Examination,
