Question

The integrable Pfaffian differential equation P dx + Q dy+Rdz = 0 reduces to ordinary differential equation under the substitution z = x + ky, k is a constant.
Answer
A. O True
B. O False​

Answer 1

Step-by-step explanation:

I think true

p dx+Q dy+R dz

if z= x+ky

P dx + Q dy + R dx + Rk dy=0

(P+R) dx + (Q+RK) dy=0
