Find the particular solution of the initial value problem.

(a) dy/dx=e^-3x+2x; y(0)=5/3

(b) given that y=sin(3x+4y) find dy/dx

I have a test on monday and a topis similar to this will be included. I would really appreciate it if somebody could show me the workings and help me understand the math, so i can try some examples by myself.

Thanks alott!!
