21==> dy/dx = 1/(x^2 + y^2)
BUT THIS WICH FORM OF DIFFERENTIAL EQUATION ??/ [7]
These are all Kaymant (Anant) Sir's questions
Q.
Suppose f(x) be a real valued function defined for all x≥1 satisfying f(1) = 1 and
f ' (x) = 1/[x2 + f(x)2]
Prove that the limit of f(x) as x goes to infinity exists and is less than
1+\pi /4
