I have retired as Professor-Mechanical in Sri Venkateswara College of Engineering and Technology under Anna University affiliated colleges in Tamil Nadu, India. I have 19 years of Industrial and 20 years of teaching experience. I am learning Maple for the past four and half years hoping to make at least one appreciable maple presentation.

## Why the time difference varies for the s...

Maple

There is a time difference variation between two clocks (0.124, 0.120) and between the same clocks for the same calculations at different times(0.07, 0.124 and 0.120, 68. What is the reason?

I redo the same programm again to see the time of performance

Now I again recall the stored time values. (unit: milliseconds). t1 and t2 are retained for ever until unassigned.

## How do I find the run time of my program...

Maple

There  are commands tic and toc in matlab program.

tic

toc

toc - tic

This gives the run time for the program.

Even in excel, we can find the difference between clock times at the start and end using NOW commands.

Is there a similar way to use maple commands to find the running time of a program.

I want to find the time taken by the student to solve the quiz questions in the enclosed doc.

## Command for animation to play on its own...

Maple

Dear friends, I have made a doc using embedded components to plot a curve. What commands should I do to animate (and pause and play using a custom play/pause button inserted in the table) the plot. Normally I have to use explore animate command, but it requires the user to use animation tools. There must be a way to do the same using play = true; loop = true commands. I donot know its use. Can any one help. Thanks.

use DocumentTools in

Do(q = %MathContainer0);
Do(p = eval(q));
# Do(%Plot0 = plot(p, x = 0..2*Pi));
Do(%Plot0 = plot(p, x = 0..10));
end use;

 Write the expression in textarea and click the button to see the plot in plot area and expression in math container

Thanks for helping out. Ramakrishnan V

## Why trigonometric properties for values ...

Maple

eval(sin(x), x = .2) is evaluated, eval(sin(x), x = 4) is not evaluated. Why? What should we do to get the answer. x-2n k (pi) can be obtained and evaluated. Why Maplesoft does not simplify and evaluate?

Is there a way out to give proper command for Maple soft to know what to do?
