hi i am vasundhara...doing my ME(Machine design) project on "Piezo-electric plate". for this i need to solve a second order differential equation which is the in the form x^2*y''+x*y'+n^2*y =f(x) ; where n is a constant.
i have taken y = y(1), y' = y(2) and y'' = y(2)'. if i give any solution for example y(x) = 2*x^2 and n=10, then i should get result (value of f(x)) in the command window. as if now i am not using any solvers or functions related to differential equations.
please help me.its urgent. my project date is approaching soon.
thank you.
with regards
vasundhara

I suggest you look at the documentation on differential equations:
