The temperature at a point (x, y) is T(x, y), measured in degrees Celsius. A bug crawls so that its position after t seconds is given by x = t sin(πt/3). y = t2 - 6t, where x and y are measured in centimeters. Find how fast temperature is changing for the bug after 2 seconds if the temperature function satisfies Tz(√3, -8) = 3 and Ty(√3, -8) = -1. Provide a graph of the bug's position during the first 6 seconds.
