What is the order of the differential equation whose solution is y=acos⁡x+bsin⁡x+ce−x+d\mathrm{y}=\mathrm{a} \cos \mathrm{x}+\mathrm{b} \sin \mathrm{x}+\mathrm{ce}^{-\mathrm{x}}+\mathrm{d}, where a,b,c\mathrm{a}, \mathrm{b}, \mathrm{c} and d are arbitrary constants?

Options

  1. A1
  2. B2
  3. C3
  4. D4

Correct answer

D. 4

Step-by-step solution

Order =4(∵=4(\because No. of arbitrary constants =4)=4)
