Two spacecraft are following paths in space given by r1=〈sin(t),t,t^2〉r1=〈sin⁡(t),t,t^2〉 and r2=〈cos(t),1−t,t^3〉.r2=〈cos⁡(t),1−t,t^3〉. If the temperature for the points is given by T(x,y,z)=x^2y(5−z),T(x,y,z)=x^2y(5−z), use the Chain Rule to determine the rate of change of the difference D in the temperatures the two spacecraft experience at time t=2. (Use decimal notation. Give your answer to two decimal places.)
