1. In class, we have discussed the following theorem: "When the domains of r and y are not dependent, then X and Y are independent if and only if fx,y(x, y) -g(x)h(y) for all r, y for some functions g and h." In this exercise, we will explore what happens if the domains of r and y are dependent Let fxy(x, y) = 6x for 0 < x < y < 1. (a) Sketch the region 0 < x <...

3. In class we discussed the heat conduction problem with the boundary conditions a(0, t) 0, t4(1,t)-0, t > 0 and the initial condition u(r,0) f(a) We found the solution to be of the form where (2n-1)n 1,2,3,. TL 20 Now consider the heat conduction problem with the boundary conditions u(0, t) 1,u(T, t)0, t>0 and the initial condition ur,0) 0. Find u(r,t). Hint: First you must find the steady state.

In class, we analyzed Buffon's needle experiment. We showed that if a large sheet of paper has parallel lines that are 1 inch apart, and we throw a needle of length 1/2 inch at it, the probability that the needle hits a line is l/r. We can estimate π by throwing many needles and seeing how many throws hit a line. Suppose we throw a needle n times, and each throw is independent. Let X be the number of throws...

1. Consider the pendulum model that we discussed in class. It's also on page 71 of the lecture notes 4. Again, for simplicity, we assume m-1-1-1 Suppose in addition we consider a damping force of this model as follows. The magnitude of the damping force is proptional to angular velocity while its direction is opposite to the one of the angular velocity. For simplicity, we may assume the damping force to be -' Then the net external torque become τ...

1. In class we derived how a transformer can up or downregulate
the voltage in an electrical circuit with an alternating
current.
(a) Use the conservation of energy to deduce how the currents I1
and I2 must be related if you know the ratio of ε1/ε2 (for the
purpose of calculating the power delivered by a circuit ignore any
complications due to the fact that I(t) and ε(t) are
time-varying).
(b) In class I argued that power transmission is more...

1 Tasks In the class, we showed that a magnet free falling inside a copper tube experiences a braking force that slows down its fall. You are to re-explain this phenomenon using approximate yet sufficient detail math description and validate the explanation using simulation to validate the experimental observation. The tasks are: 1) Refer to the diagram on Appendix A, sketch clearly in your own interpretation of the Faraday's and Lorentz's law in the dash magenta oval in the diagram...
