Question

Doing textbook problems for quiz prep. Can you show me how to solve number 4? Show each step please, even the oness you feel are obvious.

In Exercises 1-5 find ſc M(x, y) dx + N(x, y) dy, where C is
oriented counterclockwise.
1. M(x, y) = y, N(x, y) = 0; C is composed of the portion of
the quarter circle x² + 1² = 4 in the first quadrant and of
the intervals [0, 2] on the x and y axes.
2. M(x, y) = 0, N(x, y) = x; C is the circle x² + 1 2² = 9.
3. M(x, y) = xy, N(x, y) = x³/2 + y³/2; C is the square with
vertices (0, 0), (1, 0), (1, 1), and (0, 1).
4. M(x, y) = y cos x, N(x, y) = x sin y; C is the triangle with
vertices (0, 0), (π/2, 0), and (0, π/2).
