## Can you please not using...

Can you please not using maple tag? Because it doesn't work in my computer (I have no idea why though).

Here's what I did:

a[1]:=1;

seq(assign(a[n], a[n-1]+1/2^(n-1)), n = 2 .. 10);

Maple reutrns Error, (in assign) invalid arguments.

I think it's pretty close though. :)

EDIT: I don't know why, it works after I restarted maple. Thank you VERY MUCH Scott! I'll flag this one "important" :)

## For some reason, I can't...

For some reason, I can't open the file. Can you upload to another location?

## Actually, I expected this is...

Actually, I expected this is an integrated feature. What I wanted to do is to stretch a slope fields of a DE.

Since this isn't something in the exam, I'll put it till later I guess.

Thanks for all of you who responded to this topic. You're the best :)

## Yes. With maple 11, you can...

Yes. With maple 11, you can go to Tools->Tutor->Student Calculus 1->Integration Methods. There's an interface for it.

You may also let Maple show how to use integration by using

with(Student[Calculus1]):

Hint(Int(f(x), x));

Rule[%](Int(f(x),x));

You may repeat this multiple times until it is copmleted

## I think you plotted the...

I think you plotted the function correctly if you meant to plot cos(20*Pi*t). The reason it didn't look symmetrical is that you set a too big domain. Try t=-0.5..0.5, and you'll see what it's really supposed to be.

Also, you could change the style to point instead of line, or you could use the command:

plot(cos(20*Pi*t),t=-5..5,numpoints=200);

plot(cos(20*Pi*t),t=-5..5,numpoints=250);

to get more detailed plots

P.S.: You beat me in posting lol!

## If you are programming and...

If you are programming and you would like to have a better display, simplify use the command

printf("e=%a",e);
