Let f be continuous on a rectangle $Q=[a, b] \times[c, d]$. For each interior point $\left(x_{1}, x_{2}\right)$ in Q, define $F\left(x_{1}, x_{2}\right)=\int_{a}^{x_{1}}\left(\int_{c}^{x_{2}} f(x, y) d y\right) d x$. Prove that $D_{1,2} F\left(x_{1}, x_{2}\right)=D_{2,1} F\left(x_{1}, x_{2}\right)=f\left(x_{1}, x_{2}\right)$.
