 Author Comment/Response Eddie 12/27/10 10:59am Hi all, I am new to mathematica and having some teething problems. I wish to find the particular solution to e^x dy/dx =4 given that y(0)=3 Below is my attempt: (*Assign the rule above to something like 'sol' if you want to use it as a function*) eqn=e^x*y'[x]?4 sol=DSolve[eqn,y,x] ex y˘[x]?4 {{y®Function[{x},C[1]-(4 e-x)/Log[e]]}} (*verify the solution*) eqn/.sol {True} f[x_]=y/.sol[[1]] {True} Function[{x},C[1]-(4 e-x)/Log[e]] (*equation with intial conditions*) sol=DSolve[{eqn,y[0]?3},y,x] Function[{x},C[1]-(4 e-x)/Log[e]] {{y®Function[{x},(e-x (-4+4 ex+3 ex Log[e]))/Log[e]]}} Any help will be appreciated. Thanks Eddie URL: ,
