a) 1 b) 1 c) 3 d) 2
Work Step by Step
a) Order of the equation is the order of the highest order derivative and that is 1 here. b) Order of the highest order derivative= 1= order of the equation. c) This equation involve the highest order derivative of third order. Therefore, the order of this equation is 3. d) Order of highest order derivative= order of the equation= 2.
