Code:

`y=2xy[SUP]1[/SUP]+y(y[SUP]1[/SUP])[SUP]2[/SUP]; y[SUP]2[/SUP]=C[SUB]1[/SUB](x+1/4C[SUB]1[/SUB])`

So, the solution says to implicitly differentiate and gives

Code:

`y[SUP]1[/SUP]=C[SUB]1[/SUB]/2y`

So, how did they get the derivative to be this? This is the first chapter in my DE class and I'm rusty with my integrals and derivatives, been about 2 years since my calc classes.

Thanks for any help...
