Using greens theorem determine the area of the triangle with the vertices (a,b) (c,d) (e,f)
a.) draw a picture of the triangle with the vertices labled 
b.) Using vectors find an equation for the area of the triangle
c.) state greens theorem for this problem
d.) find ∫C1xdy-ydx where C1 is the line connecting (a,b) to (c,d)
e.) find ∫C2xdy-ydx where C2 is the line connecting (c,d) to (e,f)
f.)  find ∫C3xdy-ydx where C3 is the line connecting (e,f) to (a,b)
g.) find ∫C1xdy-ydx + ∫C2xdy-ydx + ∫C3xdy-ydx
h.) How is this result related to area found in part b
i.) using the result develop a general formula for the area of a polygon with known verticies
j.) Using this equation find the area of a pentagon with the verticies (3,-1) (4,2) (1,6) (-3,4) (-2,-1)
