The order and degree of the differential equation \(\frac{d^3y}{dx^3}+\cos\left(\frac{d^2 y}{dx^2}\right)=0\) are respectively
Answer & explanation
Correct answer: option 4
Degree is not defined : When dy/dx is inside a trigonometric function.
The order and degree of the differential equation \(\frac{d^3y}{dx^3}+\cos\left(\frac{d^2 y}{dx^2}\right)=0\) are respectively
Correct answer: option 4
