Here is my working so far

S1:=unapply(u*FresnelS(u)+((1/Pi)*cos((1/2)*Pi*u^2))-(1/Pi),u);

C1:=unapply(u*FresnelC(u)-((1/Pi)*sin((1/2)*Pi*u^2)),u);

with(plottools);

with(plots);

u0:=sqrt(0.25);

evalf(FresnelC(u0)+FresnelS(u0)*cot((3*Pi)/8));

p1:=display(plot([FresnelC(u),FresnelS(u),u=0..u0]));

p2:=display(plot(x-0.5191572775,x=0..1,y=0..1,colour=black));

display(p1,p2);

Hi, all, I have a question about how to compute inverse of matrix over field. Here field is actually GF(2)={0,1}. The description of MatrixInverse is here: LinearAlgebra[Generic][MatrixInverse] - compute the inverse of a square Matrix MatrixInverse[F](A) Parameters: F: the domain of computation, a field A: rectangular Matrix over values in F How to describe the F here? For example, how to illustrate {0,1} here? Thanks a lot.

Why does Maple squawk when I submit more equations than it needs for FSOLVE?  Shouldn't Maple be able to tell that the first equation is dependent on the next two equations and ignore it?  Why can't SOLVE simply output the solutions as shown in the comment line instead of giving me all that razzamatazz about RootOf this and RootOfthat?  Thanks, Ratch

I dont know if I am suppose to post this in the Get Help Forum;

So I am trying to get ready for a skills test in using Maple and I am stuck on a couple review questions, I know they seem simple but I am really new at Maple.  Help Please?

Question:

Find the arc length of the curve y^2 + y = x with positive y-values from x =1 to x = 6 in two different ways and plot the graph of the curve with MAPLE.

 

Thanks

 

Hi, all, I have a confusion when I made a newline in worksheet mode. Usually, when I hit "shift+enter", then a newline is got. However, I found that in worksheet mode, when I hit "shift+enter", there is a newline, but there is no arrow appearing at the beginning of the newline while other worksheet file (not mine) has such a arrow at the beginning of each new line. any idea? my maple is maple12. thanks

I am trying to plot four different DEs on one graph, but Maple does not like the fact that I have several constants that are not assigned to numerical values.  Here is my code:

Hi,

How would the parametric equation for the following cylinder be like?

 

Cylinder: x^2 + y^2 = a*x  where a > 0

 

Thanks

 

 

my system [u(t),v(t),w(t)] is highly non-linear. I want to understand the local behavior at [u=0,v=0,w=0]. The boundary conditions are as follows: u(0) is given but v(0) and w(0) are not. I want to know if there is a suitable choice of v(0) and w(0) such that the system will converge to the critical point [0,0,0].

Can this system be approximated by a linear system? Or by a two-dimensional system?

Hello,

Questions,

Can I use the solve function with complex number?

i.e) a simple example

7 = solve(magnitude((2+j7) / (1+j*x), x)

How to implement the above to solve x in Maple?

seems Maple doesn't treat the complex sign of j as complex.

ie)
solve(sqrt(5)=abs(1+k*I), k);

I got k as
-I*(5^(1/2)-1), (5^(1/2)+1)*I

I might expect the k for 2.

Thanks,

 

 

How do I go about calculating a chi value for a fit line?

Hi

I am trying to create a procedure for the Simpson function and i can't see why it is wrong.

This is what i have done but it keeps coming up with an error.

hi everyone,

how do I tell maple that an undefined constant e.g. K is positive and real, so that the command abs(K) results in K and not |K|?

Is there a general way of applying rules and bounds on constants without defining them directly?

thanks.

I would like to construct a Matrix containing the output of a function f(x,y) for different values of x and y, with the x-values varying (say) along the column and the y-values varying along the row.

I am studying the Julia sets and Mandelbrot. I know how to generate them. I know how to animate a simple function in the real field but until now not able to animate the Julia sets and the Mandelbrot. Is there any user guide or examples that explaines how to animate these two things in 2-D or 3-D?  I already have the user manual guide and the advanced programming guide downloaded from maplesoft but they do not contain any information or examples about what I am looking for.

Assume we have several impedance connected in parallel.

R1, L1, C1, R2

In Mathematics,

R_total = R1 || sL1 || 1/sC1 || R2

Is there possible to calculate the R_total using one of Maple function??
