Title: Test 1 Main E Problem 1
Post by: marufkaratekin on October 15, 2020, 08:58:10 AM
Was anyone who had this test able to solve Problem 1? I have been trying for over an hour and I think there might be a mistake in the question but I am not certain. Is it solvable? I would like to solve it if possible.

I also had Problem 1 E and I had the same issue, I couldn't seem to solve for the integrating factor.

Here is my solution to integral factor in question1(a), it is matter with both x and y so I used another formula:(Nx-My)/(x*M-y*N).
