14: Define a function f(x), and plot it

Define f(x) = 2e^-x/8sin(1.2x), and plot it over [0,10]

Mathematica: f[x_] := 2Exp[-x/8]Sin[1.2x] Plot[ f[x], {x,0,10} ];	Matlab: syms x y y = 2*exp(-x/8)*sin(1.2*x) ezplot(y, [0,10])
Maple: xxx	IDL: You can define a function in IDL, but plotting always involves discrete data points, so one way or another one must calculate an array y of points. x = 0.1 * fltarr(101) y = 2.0 * exp(-x/8) * sin(1.2 * x) plot, x, y
