Hello, my name is Calleigh and i am new to the forum! I am in Calculus II and have a few questions on some problems. I am using the textbook Calculus 8th edition by Larson, Hostetler and Edwards. Could someone please help me?(adsbygoogle = window.adsbygoogle || []).push({});

The problem is on pg 942 in chapter 13.6 in the text, number 76. It reads:

The temperature at point (x,y) on a metal plate is modeled by:

T(x,y)=400e^-((x^2+y)/2) where x>=0 and y>=0.

It asks to find the directions of no change in heat on the plate from the point (3,5).

It also asks to find the direction of greatest increase in heat from the point (3,5).

Does anyone know what this problem is talking about? Usually it helps if i can picture it in my head but i'm lost... My professor suggested drawing a picture, but i haven't the slightest clue even where to begin.

Any help would be greatly appreciated! Thanks guyssss ;)
