The questions are read solve the differential equation

a) sec(x)(dy/dx)=e^(y+sinx)

b)dy/dx= e^(2x-y)/e^(x+y)

For a all i could do was separate the right side to e^y +e^sinx while for b) I simplified to e^(x-2y). I am trying to read the text which is not much help since the sample questions are a lot more easier. Please help
