Question3. Let $G(x)=\int_{1}^{x}\left(t^{2}-2\right) d t$. Calculate $G(1), G^{\prime}(1)$, and $G^{\prime}(2)$, Then find a formula for $G(x)$.
4. Find $F(0), F^{\prime}(0)$, and $F^{\prime}(3)$, where $F(x)=\int_{0}^{x} \sqrt{t^{2}+t} d t$.
5. Find $G(1), G^{\prime}(0)$, and $G^{\prime}(\pi / 4)$, where $G(x)=\int_{1}^{x} \tan t d t$.
