The degree of the differential equation (d3y/dx3) -7( d2y/d2x)3+ (dy/dx)5 = sec2x is-
Answer & explanation
Correct answer: option 2
The degree of the differential equation is equal to the power of highert order derivative involve in the equation so the degree of the given differential equation (d3y/dx3) -7( d2y/d2x)3+ (dy/dx)5 = sec2x is 1.
