Vector Valued FunctionsJay Treiman 2008When considering the position of an airplane flying around the earth, its position is usually described by three variables: latitude,longitude, and altitude. This means that its position is describedby three functions of time. Writing the position as a vector onegets a function, 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.

<Text-field style="Heading 1" layout="Heading 1">Vector Valued Functions</Text-field>Most students in multivariate calculus have already seen some vector valued functions in the guise of paramteric curves. A parametric curve in the plane is a function that takes a parameter,real number, to points in the plane, vectors for us. The most common curve that people see is the paramterization of the unit circle in terms of arc length, 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.plot([cos(theta),sin(theta),theta=0..2*Pi],

axes=boxed,color=black,labels=["x","y","z"]);It is easy to define general vector valued functions in Maple.Here is the basic format.f := t -> [t,t^2,t^3];
spacecurve(f(t),t=-1..1,axes=boxed,
scaling=constrained,color=red);One can also use this to add functions. For example, assume thata planet is in a circular orbit around a star at 1 unit from the star with period one time unit and a moon is in a circular orbit around the planet at 1/20 th the distance from the star to the planet with period 1/14 th of a time unit. Using vector addition, one can find the motion of the moon relative to the star.Note the use of the unapply command to form a new function.planet := t -> <cos(t*2*Pi),sin(t*2*Pi)>;
moon_planet := t -> (1/20)*<cos(t*28*Pi),sin(t*28*Pi)>;
moon_star := unapply(planet(s)+moon_planet(s),s);
moon_star(s);Now we can plot the motion of the moon around the star.plot({[seq(planet(s)[i],i=1..2),s=0..1],[seq(moon_star(s)[i],i=1..2),s=0..1]},
color=["Green","coral"],scaling=constrained);

This is how one computes limits of vector valued functions.Here is a simple example of how this works. This is a function,the list of individual limits and the limit of the function. Seehelp on limit for the format of the command and notice the useof map to apply a function to each element of a list or array.f := t -> [1,t,t^2,t^3,t^4];
individual_limits :=
seq(limit(f(t)[i],t=a),i=1..5);
vector_limit := map(limit,f(t),t=a);
