Answer
From the question,it is given that y=
Differentiating both sides with respect to x,we get,
y' =
y' =
By differentiating (1 + x²) we get,
y' =
On simplifying we get,
y' =
By multiplying and dividing √(1 + x²)
y' =
Substituting the value of √(1 + x²)
y' =
y' =
Therefore,LHS = RHS
Therefore,the given function is a solution of the given differential equation.
hope it helps uh :)

Question
y =√1 + x²):y' = ((xy)/(1 + x²))
Solution
y = √1 + x²
dy/dx = d(√1 + x²)/dx
= 1/2√1 + x² × 2x
= x/√1 + x²
Now,We have to Verify
y' = xy/1 + x²
Taking L.H.S
y' = x/1√1 + x²
= x/√1 + x² × y/z (Multiplying and dividing by y)
= xy/√1 + x² × √1 + x² (Using by y = √1 - x² in denominator)
= xy/1 + x²
= R.H.S
Hence‚Verified...!!!!
