Bessel functions often arise in advanced engineering analyses such as the study of electric fields. Here are some selected values for the zero-order Bessel function of the first kind.
x1.82.02.22.42.6J1(x)0.58150.57670.55600.52020.4708
Estimate J1(2.1) using third- and fourth-order interpolating polynomials. Determine the percent relative error for each case based on the true value, which can be determined with MATLAB’s built-in function besselj.
