Determine the Jacobian matrix for the following isoparametric elements. If the temperatures at the nodes of both above elements are \(\left\{T_{1}, T_{2}, T_{3}, T_{4}\right\}=\{100,90,80,90\}\), compute the temperature at the midpoint of the element and at the mid point of the edge between connecting nodes 1 and 4 .
