The temperature function T(x,y) is defined on R2 by T(x, y) = xsin(2y) where T is measured in degrees Celsius and x, y are measured in centimetres. An insect is moving clockwise around the circle of radius 1 cm centred at the origin at a speed of 2 cm/sec. How fast is the temperature (experienced by the insect) changing in degrees Celsius per second at the point P(}, V3 Hint: The unit (velocity) vector of the insect at P is u = ( V3 2 ' ). Find 2D,T at P.]
