Plot parametric funcitons

19: Plot parametric functions

1. plot y=sin(x) for -10<x<10   with the axes reversed, i.e., y as the horizontal axis and x as the vertical axis
2. plot (x(t), y(t)) for 0<t<20, where x(t) = e(-0.1t)cos t   and   y(t) = e(-0.1t)sin t

Mathematica:

(1)
ParametricPlot[,,
    AxesLabel->]

(2)
ParametricPlot[ , ]

Matlab:

(1)
xxx

(2)

Maple:

IDL:

(1)
x = findgen(200)/10-10
plot, sin(x), x

(2)
t = findgen(200)/10
plot, exp(-0.1*t)*cos(t), exp(-0.1*t)*sin(t)
