Physicists know that if each edge of a thin conducting plate is kept at a constant temperature, then the temperature at the interior points is the mean (average) of the four surrounding points equidistant from the interior points. Use this principle in Exercises 69 to find the temperature at points
Hint: set up four linear equations to represent the temperature at points
