The area bounded by the parabola $$y=x^2$$ and the line $$y=x$$ is

If $$y=\sin ^{-1}\left[\cos \sqrt{\frac{1+x}{2}}\right]+x^x$$, then $$\frac{d y}{d x}$$ at $$x=1$$ is

Negation of $$(p \wedge q) \rightarrow(\sim p \vee r)$$ is

If $$A^{-1}=\left[\begin{array}{lll}3 & 2 & 6 \\ 1 & 1 & 2 \\ 2 & 5 & 5\end{array}\right]$$, then $$A=$$
