## Question:How to create an animation using a sequence of plottools[arrow]?

Maple 2016

Hello, I have been attempting to plot a sequence of arrows in order to display how the vectors of the Frenet-Serret frame change throughout an helix-like trajectory. I came up with the following:

(With p1 being a plot I made earlier)

`for t from 0 by 0.1e-1 to 12.5663706144 do plots[display](p1, plottools[arrow](Vector([cos(t), sin(t), t/(7.5)]), Vector([-(1/2)*sqrt(2)*sin(t), (1/2)*sqrt(2)*cos(t), (1/2)*sqrt(2)]), .1, .2, .3, cylindrical_arrow)) end do`

This plots the desired arrow representing the tangent vector; however, it creates a plot for each step, while what I want is for it to display the arrow on each step in the same plot (as an animation).

I have attempted using the seq command, but I can't seem to get it right.

`plots[display](p1, plottools[arrow](seq([Vector([cos(t), sin(t), t/(7.5)]), Vector([-(1/2)*sqrt(2)*sin(t), (1/2)*sqrt(2)*cos(t), (1/2)*sqrt(2)]), .1, .2, .3, cylindrical_arrow], t = 0 .. 4*Pi, 0.1e-1)))`

With this code, the sequence won't be able to be executed.

Any ideas on how to do this? How can I use the sequence command in combination with plottools[arrow]?
