Quy. 2 The Celsius temperature in a region in space is given by T (x, y, z) = 2x - xyz. A particle is moving in this region. and its position at time t is given by - , y = 3+, Z=-6 where time is distance in meters. measured in second and (a) How fast is the tempor experienced by the particle changing in dequees Celsius per meter when the particle the point P (8,6-4) is at the (b) How fast in the temperature enfrianced particle changing in degrees celsins fer second at P?
