Bessel function of the second kind, orders 0, 1, 2

\( Y_0 \left( x \right) \)

Code to plot in wxMaxima:

plot2d(bessel_y (0, x), [x, 0, 20], [y, -2, 1]);

\( Y_1 \left( x \right) \)

Code to plot in wxMaxima:

plot2d(bessel_y (1, x), [x, 0, 20], [y, -2, 1]);

\( Y_2 \left( x \right) \)

Code to plot in wxMaxima:

plot2d(bessel_y (2, x), [x, 0, 20], [y, -2, 1]);

\( Y_0 \left( x \right), \quad Y_1 \left( x \right), \quad Y_2 \left( x \right) \)

Code to plot in wxMaxima:

plot2d([bessel_y (0, x), bessel_y (1, x), bessel_y (2, x)], [x, 0, 20]);
