Question

In equation of the form Mdx+Ndy=0 where N is the function of
(A) x only
(B) y only
(C) both A and B true
(D) none of these​

Answer 1

Answer:

x only is the write answers

Answer 2

SOLUTION

TO CHOOSE THE CORRECT OPTION

In equation of the form M dx + N dy = 0 where N is the function of

(A) x only

(B) y only

(C) both A and B true

(D) none of these

EVALUATION

A differential equation of the form

M(x, y) dx + N(x, y) dy = 0

is said to be exact if its left hand member is the exact differential of some function u(x, y) i.e

du ≡ M dx + N dy = 0

Its solution , therefore , is u(x, y) = c

From above we can conclude that N is the function of x and y

FINAL ANSWER

Hence the correct option is

(C) both A and B true
