I'm not sure what is this question asking about.
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 , where x and y are measured in centimeters. The temperature function satisfies Tx(2,3) = 4 and Ty(2,3)=3. How fast is the temperature rising on the bug’s path
after 3 seconds?
How can I begin with this?
Thank you.
