#### Chain rule arcsin

Let $f$ be a continuous function on $\mathbb{R}$ and $g$ the function $g(x)=\pi-\arcsin(3+2x)$. Knowing that $f\left(\pi\right)=0$ and $f'\left(\pi\right)=-1$, find the value of the derivative $\left(f\left(g\left(-\frac{3}{2}\right)\right)\right)'$.

#### Chain rule arcsin

Let $y=y(x)=\arcsin(2-3x)$ and $x=x(t)=e^{3t^2}$.
Use the chain rule formula to express the derivative $\left.\frac{dy}{dt}\right|_{t=0}$.
