Explore the connection between the graph of a function,
f(x,y)
, of two variables and the graphs of its partial derivative functions,
f
x
(x,y)
and
f
x
(x,y)
. The "show curve" option highlights the curves obtained by taking a fixed value of one of the variables in
f(x,y)
and one of its partial derivatives. The "show projection" option plots just these two curves in two dimensions for a better view of their relationship.
