sort of tough.but can be solved?

3e^x tan y dx + (1+e^x)sec^2y dy=0\n\n(1+e^x)sec^2y dy = -3e^x tan y dx\n\nsec^2y/tany dy = -3e^x/(1+e^x) dx\n\nIntegrate both sides.\n\nln(tan y) = -3ln(1+e^x)\n\ntan y = (1+e^x)^(-3) \n\ny = arctan((1 + e^x)^(-3)

Hopefully, but it will be a struggle.

Probably not. Too much work.

No.......but you could work on the problem and actually devise something that works.

If its that hard to figure out, maybe neither one of them

i do not think so.\nand the problem is not solvable....\n'

Wow, that does not sound like an easy problem to deal with.  I suppose you have to do it as gently as possible.  I wish all the luck in doing that.
