2. The zeroth order cylindrical Bessel function has the Maclaurin series Jo (0) [(+1)* 2:12 () * k=0 Jole) = -16 () To observe a Bessel function, excite a wave on the surface of your morning cup of coffee. Jo(2) models the wave height as a function of radius. (a) Write a MATLAB function ApproxBesselJ0(x) to approximate J.(x) as a Maclaurin-Taylor polynomial, N Jo(2) k=0 where I should be a vector argument in your function. Determine the truncation N so that the size of the last term (N!) -2 2/2 2N is less than 10-8 (since x will be a vector, use MATLAB's max function to find where this last term is largest). For full credit your function must be efficient. (b) Use your function as well as MATLAB's built-in besselJ(0,x) to plot Jo(2) for 0
