Try entering:

r(t)=<2cos(t),2sin(t)>

at wolfram alpha:

Wolfram|Alpha: Computational Knowledge Engine

It will give you plots of the components, and a parametric plot, as well as the vector length.

I want some that i can plot 3D vector functions and interact with the function mode to further facilitate my study in Calculos II. I have here the Mathematica 9, im trying but i still not able to plotTry entering:

The mathematica command for what you'd like to plot would beI want some that i can plot 3D vector functions and interact with the function mode to further facilitate my study in Calculos II. I have here the Mathematica 9, im trying but i still not able to plot

Code:

`ParametricPlot[{2 Cos[t], 2 Sin[t]}, {t, 0, 2 Pi}]`

Code:

```
Manipulate[ParametricPlot[{a Cos[2 Pi b t], a Sin[2 Pi b t]}, {t, 0, 1},
PlotRange -> 10], {{a, 1}, 0.1, 10}, {{b, 0.5}, -1, 1}]
```

slight improvement:

Code:

```
Manipulate[
ParametricPlot[{a Cos[2 Pi b t], a Sin[2 Pi b t]}, {t, 0, 1},
PlotRange -> 10,
PlotLabel ->
Style[ToExpression[
StringJoin["\[LeftAngleBracket]", ToString[a], "Sin[2\[Pi]*",
ToString[b], "t],Cos[2\[Pi]*", ToString[b],
"t]\[RightAngleBracket]"]]]]
, {{a, 5}, 0.1, 10}, {{b, 0.5}, -1, 1}]
```
