Question

Write the sum of the order and the degree of the differential equation.

\(\frac {d}{dx}\left(\frac{dy}{dx}\right)=5\)

(a) 2 

(b) 1 

(c) 3 

(d) 4

Answer 1

Correct option is (c) 3 

We have,

\(\frac {d}{dx}\left(\frac{dy}{dx}\right)=5\) ⇒ \(\frac{d^2y}{dx^2}=5\)

∴ Order = 2 ; Degree = 1 

∴ Required sum = 3
