a) Triangular co-ordinates
b) ξ-,η-Co-ordinates
c) Area co-ordinates
d) Surface co-ordinates
Answer: c
Explanation: The shape function is a function which interpolates the solution between discrete values obtained at the mesh nodes. Therefore appropriate functions have to be used and as already mentioned; low order typical polynomials are used in shape functions. The shape functions are physically represented by area co-ordinates.
