Question

Find order and the degree of the differential equation. (Dy/dx)³ -4 (d²y/dx²) +7y = sin x
​

Answer 1

$\mathtt{\huge{\underline{\pink{\bf{Answer}}}}}$

$( \dfrac{dy}{dx} ) {}^{3} - 4 (\dfrac{d {}^{2}y }{dx {}^{2} }) + 7y \: = sinx$

• Order = 2

• Degree = not defined

Diffrential eqation :-

An equation containing an independent variable & differential variable independent variable is called a differential equation.

Order of Diffrential eqation :-

The order of a differential equation is the order of the highest order derivative appearing in the equation.

Degree Of Diffrential eqation :-
