was just wondering how i'd go about using the method of undetermined coefficients to find a particular solution of
y"=a
the only solution i've come up with seems too simple.
any help is greatly appreciated!
i donot know what are undetermined coefficients. but the solution to your equation will be ax^2/2+c1.x+c2 where c1 and c2 are "undetermined coefficients"(saying literally) which you can find out if some initial value is given.

This is actually a simple problem.
The Fundamental solutions are Y(t)=x+yt, where x,y is constant
so let the particular solution has the form of $\displaystyle Y(t)=At^2 $.
Then, Y"=2A, then sub it back to the equation and you will get 2A=a.
so A =a/2.
