Answer» Correct Answer - Option 2 : Non-linear of degree 2 and order 1 Concept: The order of a differential equation is the order of the highest derivative appearing in it. The degree of a differential equation is the degree of the highest derivative occurring in it, after the equation has been expressed in a form free from radicals as far as the derivatives are concerned. A differential equation is said to be linear when
Calculation: Given differential equation is \(\rm {\left(dy\over dx\right)}^2 - xy = x^3y^4\) Here x is the independent variable y is the dependent variable Highest derivate is \(\rm dy\over dx\) So, the order of the given differential equation = 1 The power of the highest derivate = 2 So, the degree of the given differential equation = 2 As the power of is 2 it is non-linear |
