Question

The order and degree of :

A) $y=1+{\left(\frac{dy}{dx}\right)}^1+\frac{1}{2!}{\left(\frac{dy}{dx}\right)}^2+\frac{1}{3!}{\left(\frac{dy}{dx}\right)}^3+.....$

B) $\frac{d^{2}y}{d{x}^2}=xlog\left(\frac{dy}{dx}\right)$

• A. order 1 degree 1 for A order 2 degree not defined for B
• B. order 1 degree not defined for A order 2 degree not defined for B
• C. order and degree not defined for both A and B
• D. order 1 degree not defined for A, order 2degree 1 for B

Answer 1

The correct option is A order 1 degree 1 for A order 2 degree not defined for B

of A) order=1 $y=e^{dy/dx}\Rightarrow logy\Rightarrow$ degree=1
of B) degree = cannot be defined order=2
