This is what I did:

It seems like it's working. But is there a way to make the time spit out time smaller than seconds? And to automatically generate how much time it took rather than me looking at it and saying "well 43 seconds minus 41 seconds is 2 seconds"? I suspect there might be.

The rest of the sheet is pretty long. NN is a uniform distribution, which worked fine.

I suspect the issue is the Pi. How can I make it give me a histogram with a numerical solution instead?

My code

Let

But checkInSet(M, (a-2*b-2*c)^2*(2*a-b+2*c)^2) not work? Someone please help me.

Thanks you very much.

when i use the command evalf(Int(f(y),y=-b..b)), i expect that the output of this command to be an integer. but the output is to form of below:

i think that the problem is because of the form of the function f(y) that is the form of below:

f(y) = a*10^354*(b*10^-356*g(sin(y) , cos(y) and exp(y)))

but i dont know how i solve this problem:(

please help me. thank you

if just expect to find whether equation is like

(a-b)*(c-d) + (e-f)*(g-h) = i

if use equal , it will care the variable name, is it possible treat the variable name as a wildcard to match the equation structure only 

the structure i mean is *, +, -, =, ()

I followed the steps given in the example of Maple help "Example 5: Adding a MathMLViewer Region" but I get the next error window.

Do you know what is my mistake?

thank you.

I am experimenting with rotating a group of pionts, lines cylinders etc. the only aminations that  will display are where I put the transformations directly as the point coordinates. This is very tedious. Is there a way around this problem efficiently? Attached worksheet shows problem(s). Ultimately I will have a whole group of objects to rotate.

The same xmaple will start graphically if I connect with a normal remote X connection. However a normal remote X connection is unusable on a slow network connection.

I have 5 equations mentioned as below,

a[0]=L+(2*beta*mu)/(3*alpha*omega^2);

a[1]=sqrt((4*mu)/(3*alpha*omega^2));

a[2]=(2*beta*mu)/(9*alpha*omega^2);

a[3]=sqrt(mu^3/(432*alpha*omega^2));

omega[s]=omega-(mu^2/16*omega)-((2*beta^2mu)/(9*alpha*omega));

Left-hand parameters i.e. a[0],a[1],a[2],a[3], omega[s] are known , and each equation on right hand contain unkonowns i.e alpha, mu, beta, omega.

I want expression for unknowns in terms of knowns.

Hello,

Maple 2016 used to work fine on my PC but now it won't even load. Whenever I try to click the program I can see the loading icon next to the cursor and then nothing happens next. It works fine on my laptop and I'm using the program under a univsersity license. Yesterday I was able to open it once for some reason and now it's the same as before. I've tried uninstalling it again and again several time but that doesn't work.

Any help would be much appreaciated.

I have a problem in this form:

a₁x₁₊a₁x_1+...a_nx₁ +(x₁)³ = b₁

a₁x₂₊a₁x_2+...a_nx₂ +(x₂)³ = b₂

..........................................

a₁x_n+a₁x_n+...a_nx_n +(x_n)³ = b_n

Here, x_1,x_2,.......,x_n  are unknowns, a₁,a₂,...,a_n and b₁,b₂,...,b_n are known contants.

Is there a possible way to find unknowns?

Hello!

I was creating this code for the "Müller Method" for Numerical Analysis. Everything works fine till the if (for getting the x3) goes on. The problem is, the Maple doesn't detects the if.
I tried checking every variable and every variable is calculated except "x3"; even "disc".

I would like to know what happened. Anyways, here's the code:
http://imgur.com/a/DGlgl
 

                     
x0 := 0; x1 := 8.4; x2 := 10; iter := 1000; tol := 10^(-8); f := proc (x) options operator, arrow; 3*x^3+7*x^2+x+2 end proc; f(x); plot(f(x), color = green); printf(" n          x0               x1               x2              x3                Error \n"); for i to iter do d0 := evalf((f(x1)-f(x0))/(x1-x0)); d1 := evalf((f(x2)-f(x1))/(x2-x1)); h1 := evalf(x2-x1); h0 := evalf(x1-x0); a := evalf((d1-d0)/(h1-h0)); b := evalf(a*h1+d1); c := evalf(f(x2)); disc := sqrt(-4*a*c+b^2); if abs(b+disc) > abs(b-disc) then x3 := x2+(-2*c)*(1/(b+sqrt(-4*a*c+b^2))); erry := abs((x3-x2)/x3) else x3 := x2+(-2*c)*(1/(b-sqrt(-4*a*c+b^2))); erry := abs((x3-x2)/x3) end if; if erry > tol then x0 := x1; x1 := x2; x2 := x3; printf("%2d     %2.8f      %2.8f       %2.8f         %2.5 f     %2.8 f \n", i, a, b, c, x3, erry) else printf("una raiz es: %2.8f ", x3); break end if end do;

I put the image (as it looks on my maple) and the "code" so you can copy-paste it in Maple.

Hello everyone,

I have 5 equations (fa,fb,fc,fk,fv) and 5 variables (V0,A0,A1,A2,k1) and I want to solve them numerically. Problem is my inability to set properly intervals and starting values. 

Here is my command: fsolve({fa,fb,fc,fk,fv},{V0,A0,A1,A2,k1});

If I run it just like this, I get some values, lets say V0=0.00045 etc.But when I set range for V0 like this:

fsolve({fa,fb,fc,fk,fv},{V0=0.0004..0.0005,A0,A1,A2,k1});

I get this:

Error, (in fsolve) fsolve cannot solve on V0 = 0.4e-3 .. 0.5e-3

I used interval 0.0004..0.0005 only to prove that there must be the wrong syntax, because obviously 0.0004<0.00045<0.0005. In reality i need interval 0.0001..0.0002 and it is also necessary.to set some initial values (A0=0.0023) but first I need to solve my problem with syntax.

Any advice ?
