Use the "mixed partials" check to see if the following differential equation is exact. if it is exact find a function f(x, y) whose differential, df(x, y) is the left hand side of the differential equation. that is, level curves f(x, y)=c are solutions to the differential equation (1exsin(y)+3y)dx+(3x+1excos(y))dy=0

Me with this assignment ! i only partially understand, so explain. also it's a work sample. at the championship bike race, steve and paula were fighting for first place. steve was 175 feet ahead of paula and had only 300 feet left to go. he was very tired and was going only 9 feet per second. paula was desperate to catch up and was going 15 feet per second. who won the bike race and by how far did she/he win?
