In a series cutting experiments, Jimmy summarized the
relationship between force to cut the material and the heat released
from the material. The heat is a piecewise continuous function of force.
He wants to analysis the heat released when force is 1 and 2 kN. The
function is:
Since f(x) is a piecewise function, the functions for f(x) on the left
and right hand side of 1 kN and 2 kN. The way to analysis the boundary
heat conductive is to consider both side heat conductive at the boundary.
First, consider the case of x approaches 1^{}:
