Consider the differential equation: 7e= + (81y° sec(2y) – 2e= tan(2y))y/ = 0. a. This equation is not exact because M, = does not equal N, b. Find an integrating factor, µ, to make the equation exact. Do not include an arbitrary constant in your answer for H. By assuming that µ is a function of only (enter a or y), we get that µ= c. Using the integrating factor, we get that the general solution is V(x, y) = = C.
