1) Could you please demonstrate the algebra going from
1/4 ln (u) = sinx + c to [u]=Ae^(4sin(x)) and How is the second function similar to ln(y^(4)+1)= C+ 4sin(x)
I would like to know how 4 ended up being part of the exponent. (I forgot how to solve)
2) How would you simplify e^(y) = 3e^(2x)+C by solving for y?
(The back of my book has the final answer as y= ln(3e^(2x)-2)
I do not understand where the -2 comes from. Here's what the original problem said in case you need to refer to it:
*Find an explicit particular solution of the initial problem :
dy/dx= 6e^(2x-y) , y(0)=0.
