2nd ordr homogenoues ODEs

the behavoiur of the solution of d^2x/dt^2+adx/dt+4x
depends on the value of a
Note a=alpha

a)find the ranges of a so that the solution displays

i)overdamping
ii)critical damping
iii)underdamping(decaying oscilations)
iv)growing oscilations
v)constant oscilations

b)For each of these cases, choose value of a within your stated
ranges, and find the general solution, displaying your solution
pictorially to show the behaviour of the solution

c) By carefully considering all the possible values of a identify the ranes which do not lead to the behavouirs listed in a, and describe the typical behaviour in this case

You have not given an equation... I expect you meant .

Anyway, I suggest you read this article.

thanks, how do u write the eqaution like that, wihout useing / or a?
