Path Integral of Triangle: Parameterization & Solution Explanation

Click For Summary
SUMMARY

The discussion focuses on calculating the line integral of the vector field F(x,y,z) = (e^z, e^y, x+y) along a triangular path defined by the vertices (1,0,0), (0,1,0), and (0,0,1). The parameterization of the path is broken down into three segments: C1, C2, and C3, with specific equations provided for each segment. The user attempts to express the integral as F(c(t)) * c'(t) dt, confirming the correct parameterization for each segment of the triangle.

Homework Statement




The problem asks:

find the integral of gamma F.ds where F(x,y,z) = (e^z, e^y, x+y).
gamma being a triangle with vertices:

(1,0,0) (0,1,0) (0,0,1) going in a counterclockwise direction

Homework Equations





The Attempt at a Solution



So I'm not even sure if what I'm doing is right. This is my attempt to parameterize

C1: x = t, y = 1-t, z = 0 for 0<t<1
C2: x = 2-t, y = 0, z = 1-t for 1<t<2
C3: x = 0, y = t-2, z = 3-t for 2<t<3

And to find the integral it's

F(c(t))*c'(t) dt

is that right?

It should be:
##C_1:\vec r=(1-t,t,0),0\le t\le1.##
##C_2:\vec r=(0,1-t,t),0\le t\le1.##
##C_3:\vec r=(t,0,1-t),0\le t\le1.##
 
Make a drawing, and show which lines are C1,C2,C3.
