How would I be able to sketch the graph in problem 7.36?
A triangle in the xy plane is defined with
corners at (x, y) = (0,0), (0, 2) and
(4, 2). We want to integrate some
function f(x, y) over the interior of this
triangle.
Choosing dx as the inner integral, the
required expression to integrate is given
by:
Select one:
o Sro S-o f(x, y) dx dy
x=0
2y
y=0
O S-o So F(x, y) dæ dy
O o S f(x, y) dy dæ
O So So F(x, y) dx dy
x/2
=0
The following problem involves an equation of the form = f(y).

Sketch the graph of f(y) versus y, determine the critical (equilibrium)
points, and classify each one as asymptotically stable or unstable.
Draw the phase line, and sketch several graphs of solutions in the
ty-plane.
