Question
This exercise is adapted from a problem from the textbook.

Consider the line integral

\[
\int_{C} (x-y) \, dx + (x+y) \, dy
\]

where \( C \) is the curve going counterclockwise around the triangle with vertices \( (0,0) \), \( (1,0) \), and \( (0,1) \).

(a) Sketch a graph of the triangle described above. Indicate the direction of the curve on the triangle.

(b) Find parameterizations of the three line segments forming the edges of the triangle. *Note: This works the same way that it did in 3D with \( t \), except with two components each instead of three. Review Section 12.5 for details.*

(c) Evaluate the integral above by first expressing the line integral as a single-variable in terms of the parameter \( t \).
