## 3. A simple element analysis (cont'd)

The **Cartesian-coördinate** method
involves choosing as basis
functions the set \(\{1, x, y\}\).
The displacement at any
point \((x, y)\) in the element is then given by a linear
combination of these three functions, namely,

$w(x,y)={c}_{1}+{c}_{2}x+{c}_{3}y$ | (Eqn. 5) |
