3. (a) Let $D = [-\pi, \pi] \times [-\pi, \pi]$. Show that $$ \frac{1}{e} \le \frac{1}{4\pi^2} \iint_D e^{\sin(x^2+y^2)} dA \le e. $$ (b) Let $D$ be the triangle with vertices at $(0, 0)$, $(1, 1)$ and $(1, 0)$. Show that $$ \frac{1}{6} \le \iint_D \frac{dA}{y - x + 3} \le \frac{1}{4}. $$ Note: You should read the section on Mean-Value Inequality from Section 5.4.

1) (10 pts) a) Use node voltage analysis (must use supernode) to find voltages $V_1$, $V_2$, and $V_3$. NOTE: Voltage values for the three voltages will come from this list: -30V, -26.66V, -20V, -13.33V, -10V, -5V, 0, 5V, 10V, 13.33V, 26.66V, 30V. b) Use the node voltages to find all the currents indicated: $I_1$, $I_2$ and $I_3$. c) Verify that the power delivered = power absorbed.
