hi 

if I have two partition Pi and Pi 'I want to know the decomposition of Pi' 

So I want to display a plot containing a spiral and a polygon graph approximating the shape. I use a seq to make the points in pointplot3d and then connect them with the connect option. It looks like this:

y(t):=t-><cos(t),sin(t),t>:

graph := spacecurve(y(t), t = 0 .. 6, thickness = 3, axes = box, color = blue):

poly6 := pointplot3d({seq([cos(t), sin(t), t], t = 0 .. 6, 1)}, connect, axes = box, 

color = red, thickness = 3, caption = {n = 6}):

every time I enter / or ^, maple automatically changed the text I entered into fraction or power, and I am having hard time enter equations normally like the way I do in graphic calculator or matlab. I am forced to type all my equations on a text pad and then copy over.

is there a way to stop maple from auto formatting my input text? I am more of a matlab guy and I really need to use symbolics and integration abilities right now, but this version of maple is making...

I have defined a function as follows:

f:=alpha->1-RombInt(10*tan(x)^alpha,0,Pi/4,1,2);

and now i need to plot this function to see where the root lies, i have tried to do this using the following command:

plot(10*tan(x)^alpha);

and i have tried putting in boundaries but it doesnt seem to work. Can anyone help me please.

If I have 

F = x + 2π_Z1~

Is there a function/operator I can apply to F which returns only x, discarding 2π_Z1~?  That is, I want to return only the base angle, and dump the added integer multiple of 2π term.

Hello All,

Are there keyboard shortcuts for pi and e? It's quite inconvenient to pull these from "Common Symbols". Thanks!

I need to cut a circle into equal pieces like a pizza, but how do I do this through code?

Also, I need to be able to find the area, angle, and arc length. Is this possible through code?

Thanks!

I need to create an ellipse and an ellipsoid (ellipse in 3D) through code. How would I be able to do this? Can someone please give me an example for each?

Also, I will need to create a line for an ellipse and a plane for an ellipsoid that intersect. Would I be able to find the intersecting points? Would I be able to find the function for the curve line that is created when a plane intersects an ellipsoid? Also, how would I find the surface area and volume...

Hi,

I am trying to simplify the expression s as given below. (I am not sure why it comes up with all the vector caclulus notation in it but it should display okay when you enter it)

Because of the presence of the exponential imaginary fucntions I thought evalc might be useful but when I use it I get a huge expression with csgn appearing in it. To my knowledge csgn appears when assumptions are not correctly specified - is this so? I can't see any assumption...

1-(1-x₁)(1-x₂)....(1-x_n)=1-(inverted PI).

Is there a simbol for the Inverted PI?

thanks

I understand this: 23 mod 4

 - it gives me the remainder on dividing 23 by 4

But how can I do the same thing with, say, 23.4 and 5.2?

The reason I ask is because I want to divide angles (float values) by (2*Pi) (another float) and just get the remainder, i.e. I want to discard multiples of (2*Pi) from my angle.

Hi, everyboyd I wan to draw a vertical line at theta:=Pi  for any function.

How can i do it.

In the following examples I attempt to remove integer multiples of Pi from sin/cos. Nothing works.

Why? How do I make it work?

Thank you.

term1:=cos(Pi*(3*a-2*n));
> term2:=cos(3*Pi*a+2*Pi*n);
> term3:=cos(3*Pi*a-2*Pi*n);

                     term1 := cos(Pi (3 a - 2 n))

Ive tried this for hours and can't get it to work. Any help would be greatly appreciated. I need to 

find a 10 significant figure approximation to the 10^th derivative of

evaluated at x = -2.

Ive tried using this maple command:

evalf(subs(x=-2,diff((sin((x^2...
