Short Answer

Expert verified

The graph of the function $\sqrt{x} J_{\frac{1}{2}} (x)$ is given below:

Step by step solution

Step 1: Concept of Bessel’s Equation:

The solution of Bessel's equation is, $x^{2} y " + xy' + (x^{2} - n^{2}) y = 0$ .

$J_{n} (x) = {鈭�}_{k = 0}^{鈭�} \frac{{(- 1)}^{k}}{(k + 1) 鈱� (n + k + 1)} {(\frac{x}{2})}^{2 k + n}$

Calculation of the function xJ12(x) for x :

Given function $J_{p} (x)$ for $p = \frac{1}{2}$ and x from 0 to $蟺$ .

role="math" localid="1659269941142" $J_{p} (x) = {鈭�}_{n = 0}^{鈭�} \frac{{(- 1)}^{n}}{(n + 1) 鈱� (n + 1 + p)} {(\frac{x}{2})}^{2 n + p}$

For, $p = \frac{1}{2}$ in above function.

$J_{p} (x) = {鈭�}_{n = 0}^{鈭�} \frac{{(- 1)}^{n}}{(n + 1) 鈱� (n + 1 + p)} {(\frac{x}{2})}^{2 n + p} \sqrt{x} J_{\frac{1}{2}} (x) = {鈭�}_{n = 0}^{鈭�} \frac{{(- 1)}^{n}}{(n!) (n + \frac{1}{2})!} {(\frac{x}{2})}^{2 n + \frac{1}{2} + \frac{1}{2}} (鈭� 鈱� (n + 1) = n!) \sqrt{x} J_{\frac{1}{2}} (x) = \frac{1}{(\frac{1}{2})!} (\frac{x}{2}) - \frac{1}{(\frac{3}{2})!} {(\frac{x}{2})}^{3} + (\frac{1}{2!}) \frac{1}{(\frac{5}{2})!} {(\frac{x}{2})}^{5} - (\frac{1}{3!}) \frac{1}{(\frac{7}{2})!} {(\frac{x}{2})}^{7} + (\frac{1}{4!}) \frac{1}{(\frac{9}{2})!} (\frac{x}{2}) = {(\frac{1}{5!})}^{2} - \frac{1}{(\frac{11}{2})!} {(\frac{x}{2})}^{11} + (\frac{1}{6!}) - \frac{1}{(\frac{13}{2})!} {(\frac{x}{2})}^{13} - (\frac{1}{7!}) - \frac{1}{(\frac{15}{2})!} {(\frac{x}{2})}^{15} + . . . . . .$

Draw the graph of the function xJ12(x) :

The graph of the function $\sqrt{x} J_{\frac{1}{2}} (x)$ is given below:

From the above graph, we can observe that there are three zeros of $\sqrt{x} J_{\frac{1}{2}} (x)$ from $x = 0$ to $蟺$ .
