Verify that the given differential equation is not exact. (−xy sin(x) + 2y cos(x)) dx + 2x cos(x) dy = 0 If the given DE is written in the form M(x, y) dx + N(x, y) dy = 0, one has My = $$ Correct: Your answer is correct. Nx = $$ Correct: Your answer is correct. . Since My and Nx are not Correct: Your answer is correct. equal, the equation is not exact. Multiply the given differential equation by the integrating factor μ(x, y) = xy and verify that the new equation is exact. If the new DE is written in the form M(x, y) dx + N(x, y) dy = 0, one has My = $$ Correct: Your answer is correct. Nx = $$ Correct: Your answer is correct. . Since My and Nx are Correct: Your answer is correct. equal, the equation is exact. Solve.
