A student claims that if f : [a, b] → R is such that f(x) ≥ 0 for all x ∈ [a, b], f is integrable over [a, b], and R b a f(x) dx = 0, then f(x) = 0 for all x. Show by example that their claim is incorrect.

While using the computer at the library, you notice that it does not seem to be connecting properly to the internet. After a few minutes, you give up trying to use that computer and move to a different one. Several weeks later, you are back at the library. You attempt to use the same computer that wasn't working last time, in hopes that it is now working. This behavior exemplifies O reinforcement. O discrimination. O extinction. O generalization.

Sketch the $D$ indicated and integrate $f(x, y)$ over $D$ using polar coordinates. $f(x, y) = 6xy$; $x \ge 0$, $y \ge 0$, $x^2 + y^2 \le 9$ Answer:
Problem 3: Spherical Pressure Vessel A thin-walled spherical vessel contains a pressure $p$ and has an inner radius $r$ and a wall thickness $t$. It is made of an isotropic, homogeneous material that behaves in a linear-elastic manner. Determine the following as a function of the pressure ($p$), the geometric dimensions ($r$, $t$) and the materials constants ($E$, $\nu$) involved: a) Change in radius $\Delta r$ b) Change in wall thickness $\Delta t$ For spherical pressure vessel: $\sigma_x = \sigma_y = pr/2t$, $\sigma_z = 0$
