1. The problem statement, all variables and given/known data dy/dx=y/x 2. Relevant equations 3. The attempt at a solution ok heres what I got... dy/dx=y/x so dy/y=dx/x. Then just integrate both sides and you get ln(y)=ln(x)+C. Next raise both sides to a power of e and you get y=e^(ln(x)+C). This can be rewritten y=e^ln(x)*e^C. so the answer i got is y=xe^C. however, i checked the answer in the back of my textbook and it says that the answer is y=Cx. Help please??
