ANSWER NUMBER 1 & 3 & 5. THANK U

Practice Exercise: Find the differential equations of the following by
eliminating the arbitrary
constants.
1. у %3D 2х + сех
ans: y' - у + 2х - 2 %3D 0
2. y = c,ex + C2e2x + x
ans: y" - 3y' - 2х + 2у + 3 %3D 0
3. у %3 С, ех cos3x + с, ex sin3xх
ans: y" – 2y' + 10y = 0
4. y = c, sin wt + C2 cos wt
w is a parameter
5. (у — k)2 %3D 4a (х - Һ)
parameter
parabola with vertex at (h,k), and a as
