Question 3: Exact Differential Equation
i. Test to see if the following equation is exact, if exact solve for the general solution
(??/??) +(2? ????+?^3?^?)/(?^2cos?+3?^2?^?)=0


ii. Solve (?+????)??+(?????−2?)??=0


iii. Solve (?^2+?)??+(?^?−?)??=0


iv. (2?−3?)??+(2?−3?)??=0

I am sorry I could not send a photo. Whenever I try from the app it posts another question on the same page. I tried doing them individually and the only thing that happened was that the same question got posted 4 times. I would appreciate your help in solving these. Thank you!
