Question: Derivative Syntax

This is my first time using Maple - so I don't even know where to start... Hopefully I can make this clear... example problem: f(x) = 2.3x g(x) = ax^3+bx^2+cx+d h(x) = px^2+qx+r l(x) = kx^3+mx^2+nx+s I was able to find the correct syntax for Maple to calculate the first and second derivatives of the functions above. Now I have to write out a system of equations using the original functions and their derivatives...once I have the system of equations then I need Maple to solve for each variable...what is the proper syntax for all of that? Also, for Maple to calculate the derivative I used "diff(f(x),x)" and "diff(f(x),x$2)", so how do I get those derivatives into my system of equations? TIA!!
