It turns out that nature always splits the currents so that the total energy is minimized. Find the current in each branch. Read over the next problem, and ask yourself what kind of a problem is this, and where have I seen a similar one? (Space for your answers below) 3) The temperature z in degrees centigrade at a point on a road, x meters East and y meters North from a fixed location (the origin), is given as z = f ( x, y ). If a bug at a point on the road moves East, the temperature increases at the rate of 0 . 8 degrees/meter If it moves North, the temperature decreases at the rate of 1 . 4 degrees/meter. At time t = 0, the bug decides to move along a path ( x ( t ) , y ( t )) from its current location with velocity ( x 0 (0) , y 0 (0)) = (0 . 8 , - 1 . 4) meters/minute. What is the rate of change in temperature along the bug’s path at t = 0?  #### You've reached the end of your free preview.
