Linear Differential Equations of the Second Order

Example To graph the solution of the linear differential equation of the second

order y앨 + 9y = sin 3x, x0 = 0, y0= 1, y쎾0 = 1, 0

< x

< 10, h = 0.1.

Use the following V-Window settings.

Xmin = –1, Xmax = 11, Xscale = 1

Ymin = –3.1, Ymax = 3.1, Yscale = 1
