1.	Let y=f(x), f:R→R be an odd differentiable function such that f′′′(x)>0 and g(α,β)=sin8α+cos8β+2−4sin2αcos2β. If f′′(g(α,β))=0, then sin2α+sin2β is equal to
Answer» Let $y = f (x)$ , $f : R \to R$ be an odd differentiable function such that $f^{'''} (x) > 0$ and $g (α, β) = s i n^{8} α + c o s^{8} β + 2 - 4 s i n^{2} α c o s^{2} β$ . If $f^{''} (g (α, β)) = 0$ , then $s i n^{2} α + s i n^{2} β$ is equal to
