hi!

i am new to Maple (just purchased 13) as well as trigonometry, which i am using Maple for! i'm trying to use Maple for all of my Chem and Trig homework because I am a Physics major and I think i'll probably be using this for years, so might as well get accustomed now!

basically, one of the problems has a figure with a unit circle on a cartesian plane. the "t-line" (or plot line, i dont know) has tick marks that represent the length of (t), and they go from 1 to 6. to give a better "mental image":

hi all! i am **brand new** with maple 13 as well as trigonometry, which i am using the program for. i have figured out how to plot the unit circle with the command:

Hi,

How can I add a super-script circle degrees symbol in a plot label?

E.g. plot(x^2, labels=["Distance", "Temperature (degrees celcius)"]); ... etc

Hi all,

Wondering if there is a way to change the HUE color range that will be used for listdensity plot.

Currently default setting is to use the full HUE color. But what we need is a shorter range, e.g., only from orange to blue.

Can it be achieved?

Or the PLOT structure has to be used?

This is the code i am using now.

Is there any function that we can sort a list / vector?

What abt a matrix? e.g.

M:=Matrix([[2, 5], [4, 0], [3, 9]]);

The sorted matrix (based on its first column) will be:

Matrix([[2, 5], [3, 9],[4, 0]]);

hello

I use

plots[odeplots](dsol,[t,(D(X[5](t))(t),0..5,numpoints=100);

when dsol=dsolve(..........) which is a procedure to plot first derivative of X[5] now I wanna know what should I use to plot second derivative of that

I used

plots[odeplots](dsol,[t,(D[1,1](X[5](t))(t),0..5,numpoints=100); but nothing shows up

and some other commands none of them works for me.

Thanks

bye

Is there any maple command that I can use dsolve with method=implicit I could not find that in help?

thanks

restart:
with(LinearAlgebra):
A:=RandomMatrix(3,2, generator=1..3);

                               [1   1]
                               [       ]

> A:=Matrix([[1,2,2,3],[5,1,0,4],[6,7,3,4]]);
> V:=<6,5,9>;
                            

I want to add vector V as a new column [e.g. 3rd column] in matrix A, is there any function to do that simply? What abt to add as a row?

Hi!

I have the follwing problem. I have the matrix

B C F G 7    8    9  
0  1 2 3 21 22  23

And each input of the 1st line should result in the 2nd line. E.g. Input B, should result Output  0 or Input 8 should result 22. I mean the analog function in Excel: vlookup

Is that possible?

Thank you!

Good Evening,

Would anybody please tell me what I'm doing wrong in the attached Maple worksheet. My first problem is to sum a vector and divide by the nops(x) to determine the CG of a pile group.

My second problem is a For loop with units at the bottom of the page. Please Help.

Regards,

Moses

It took me a couple of days just to write the below Maplet code which loads a CSV file (time series organized in

columns where the first column is date/year etc and first row contain the names of the stocks)

and displays the stock names in a dropdownbox. Now I want to plot my selection from my dropdownbox

but now I have a new problem. When I include the "onchange = AC"

command in the drop1 command line in order to update my selection from the dropdownBox

I get an error message :
