How would I start this one? I tried dividing by y, but that does not work
Why doesn't that work?
Yeah why does dividing by y not work?
Here's what I did:
1/y y' = x/(1+x²)
ln y = 1/2 ln (1+x²)+c
y = ce^(1/2 ln(1+x²))
Answer's supposed to be: c*sqrt(1+x²)
Yeah, ok and how is that different from what you had? Just simplify your expression with the properties of logs.
Nevermind. I get it now. Thank you :)
