Hello

I'm working on a project, where I need to create some user friendly proc/modules. I need it to ask for the variables e.i.

'Enter equation'

'Define range'

etc. but I have no idea how to do so. Can you describe a method of doing so?

With Maple15, how do I get this

sigma^2*(1+(lambda[0]+lambda[1]-2)^2+(1-lambda[0])^2)

from

with(Statistics):
R := 'RandomVariable(Normal(0, sigma))'; a := [`$`('R', 5)]
Variance((1-lambda[0])*a[3]+(lambda[0]+lambda[1]-2)*a[4]+a[5]);
simplify(%, size); collect(%, {sigma, lambda[0], lambda[1]})

In general, how do I simplify an expression when it can be stated as a sum of squares? I suspect I am missing a general simplification technique. Thanks.

Hi All

If we have extensive material in pdf format and we want to tranfer this information to Maple and use it it as the main editor and word proceesor on a go forward basis - Is it possible to copy a pdf document with extensive equations into Maple while maintaining the format particularly of the equations, pictures, drawings and plots? Any copying and pasting I do now garlbles up the equations, plots and pictures of the pages I import to Maple...

i am having a problem with this question

graph the polynomial function F(x)= x^4 - 2.5x^2 + 0.5625

determine x & y intercepts?

find local maximum And minimum of F(x)

please advise

Dear guys! I've written some expressions and then the final equations which I want to solve as below:

> Omega0 := 0.26: H0 := 0.8: q0 := -0.61: j0 := 1: s0 := -0.18: l0 := 2.61:

> f0 := 6*H0^2*(Omega0-2):      f10 := 1:    f20 := (6*H0^2)^(-1)*(-3*Omega0/(4*(1+q0))+1/2):     f30 := (6*H0^2)^(-2)*(-3*Omega0*(3*q0^2+6*q0+j0+2)/(8*(1+q0)^3)+3/4):     f40 := (6*H0^2)^(-3)*(-3*Omega0*(s0*(1+q0...

Is there a way to make the y-axis logarithmic using DEplot?

Use a change of variables to find the volume of the solid region lying below the surface f(x,y)=(2y-x)^4sqrt(x+y) and above the parallelogram in the xy=plane with vertices (3,5) (2,6) (10,10) and (11,9)

Graph the 'ice cream cone' formed ny the upper half of the sphere x^2+y^2+z^2=16 and the cone z=sqrt(x^2+y^2) using maple, and find the z-coordinates of its center of mass.

Graph the solid common to the cylinders x^2+z^2=4 and y^2+z^2=4 using maple and find the volume of the region common to the cylinders.

I'm suppose to graph the first octant portion of the surface z=4-x^2, 2≤y≤5 using maple and find the volume of the solid over the xy-plane and under the surface.

I use a for loop to step through the operands of an expression and do a calculation on each operand. I am then unable to add up or otherwise access for manipulation the result of the for loop and wondered how this could be done. What I mean is as follows. I have the expression w

w := 2*(1/2/Pi+Q*cos(k*phi))*Q*cos(k*phi)*(exp(-1/2*sigma^2*k^2)-1)*t*(1/2/Pi+Q*cos(k*psi))/(beta^2*(1+beta^2*(1/2/Pi+Q*cos(k*phi))^2))+(1/2/Pi+Q*cos(k*phi))^2*Q*cos(k*psi)*(exp(-1/2*sigma^2*k^2...

This exponent is a number of order 2011! and Maple operates with such quantities. However, the simpleminded approaches fail:
> for k to 10 do is(`in`(2^k, numtheory[divisors](factorial(2011)))) end do;

Error, (in numtheory:-divisors) object too large
 
> for k to factorial(2020) do if is((factorial(factorial(2011))/2^k)::posint) then NULL else print(k) end if end do;

Error, (in fact) Cannot allocate memory (size=100728832)

Hi,

I'm using Maple 11 and pdflatex. I'm trying to export Maple code to latex.  To this end, I've exported my maple file as a latex file and included the maplestd2e package in my tex document. However, from compiling the tex file I only obtain pdf output for those parts of the original maple file that represent output. For example, the following tex-code correctly produces the word 'true':

\mapleresult
\begin{maplelatex}
\mapleinline{inert}{2d}{true}{\[\displaystyle {\it true}\]}

Hey guys. Can you help me with this problem? I'm trying to plug in a snowflake equation in finding the perimeter of a snowflake on the nth step. The function is as follows:

p:=n->(3*(3/4)^k, k=1..n);
                                   

I'm trying to find the limit of this equation and it's suppose to give me infinity by using this command:

limit(pn(n), n=infinity);     but it's not quite giving me the limit. The limit is...
