3.) A 5.00 x 10^2g block of metal absorbs 5016 joules of heat when its temperature changes from 20 degrees C to 30 degrees C. Calculate the specific heat of the metal.

I'm using Maple TA with first-year business students.

Hey, I want to look into something about n! I wrote a procedure like: > myfactorial:=proc(N) > local ptlist,k: > uses plots: > ptlist:=NULL: > for k to N do > ptlist:=ptlist,(k,k!): > od: > pointplot([ptlist],color=red); > end: myfactorial(20); works fine myfactorial(50); and more than 50 it says floating point overflow.please shorten axes.. is there a way to make it work? and n! is defined as int(x^n*exp(1)^(-x),x=0..infinity); why the output is Gamma (n+1) insteas of 1? simplify(%/n!); # can give me "1" and how do i get maple to plot

What I mean is, I have a set of variable, and a set of equations. The thing is, there are a lot of variables, and not enough equations to uniquely determine them unless the 'rules' are applied, which are:

1) all x_i that exist are integers between 1 and 9, i.e. x_i is in {1,2,3,4,5,6,7,8,9}

2) if x_i exists, then x_i<>x_i+1 AND x_i<>x_i+10

In an effort to draw the unit normal of a vector, n, to a curve defined by a radius curve, r, the following command is inputted to Maple but recieves the error also noted below.

arrow([0,0,0],eval(convert(n,list),t=0*Pi),shape=cylindrical_arrow,color=black);

Error, (in simpl/abs) abs is not differentiable at 0

 However a plot of the components of the unit vector shows that it is well behaved at 0, i.e. it has values of <-1,0,0>

I'm trying to write a sequence on Maple11 that outputs the determinant of the vandermonde matrix for  a given n in terms of x_i, i=1...n. The procedure shud have a single argument n so that it begins VanDet:=proc(n).

PLEASE HELP

I wonder if maple has a way for multiple inputs to functions.  For example, given:

f := (x,y) → x + y

is there a way to pass in (x,y) = (0,0) AND (1,1) at the same time?   I tried:

f({0,0},{1,1})

But the output doesn't make sense to me.I have wanted this feature as long as I have had maple, but gave up on this possibility.  Now by accident I discovered something quite similar. when checking maple's solution to a system of equations.

what is the verbal representation of function mean

 

So I was searching the net and such for and idea of how to do this, i found: www.maplesoft.com/Applications/appviewer.aspx

The first example is pretty self explanitory, now my question is for more complicated functions is there a maple method to do this quicker, or do i have to do the beat it with a stick method?

 

Thanks!

Ok, I've got a matrix where the elements are lists of length 3, the first element tells you what sort of entry it is; the important thing to know here is that if the first entry is one then the second entry (and third) is a variable.

Hi, I'm currently using MAPLE 11

I'm trying to multiply series(about 30) matrix[ Matrix name is(F(x[k],y[k],j[k])) by using the product command

i.e.

product(F(x[k],y[k],j[k]), k=1..10); 

when I use the above command the following. error occurs.

[Error, (in rtable/Product) invalid arguments]

I've figured out the product command only works for real numbers, not matrix

But the problem is ... then what command should I use?

 

Greetings All

I'm having some trouble figuring out a sequence of numbers using common Difference
I've figured out the polynomial for the even numbers for the sequence but the odd numbers have a repeating pattern which I'm not sure how to create a Polynomial for.  

I've included my work here
http://demos.onewithall.net/number_patterns.jpg on the even numbers which I’ve verified and they are correct.

Ok I have already defined f as a procedure earlier on, so here is where i am having a problem:

 

Hi Guys, im wondering if you can help me with this for loop problem

so i have the array k[20,20], so it has 400 hundred entries, each entry has a number, but one entry has a number higher  then the others,

e.g. k[1,5]=6,k[1,6]=40,k[4,4]=20

so in the loop below i intend for the a and b element of the entry with the highest value to be assigned to tempa[2,1] and tempa[2,2], but i am not getting this outcome, please have a look

 

My sincere apologies for this incredibly elementary question.  I just can't find the answer.  Please refer me to an appropriate resource for this information if you know of one so that I won't bother the forum with such inane questions in the future.

Here is a simplfied example of what I'm trying to do (when my code didn't work, I created progressively simpler examples until I got to this):

--------------------------

a := array(1..3);

for i from 1 to 3 do

    a[i] := t -> i*t

end do;
