If we use numerical approximation to my integral(methods available in Student[NumericalAnalysis] package) the answer will be better or worse? I used simpson method for the my integral and i want you to compare this answer with the direct answer that we reached in the last comment..thank u so much

the first answer is the direct answer, and second & third answer is the use of simpson rule withh the numerical methods.which answer is better?

Hi there. I have two expressions of type Matrix(7x1), one I entered directly and the other one is the result of a  procedure calling. They only differ by the term [1,1], so when I do a comparation of the appropiate submatrix using Equal I get a positive answer:

>Equal(SubMatrix(atataaV(1,1,1,1,u1),2..-1,1),SubMatrix(u1,2..-1,1));

true

Now, the elements of the submatrices depend on the symbol 'n',...

I'm brand new to Maple. How can I plot the Gammafunction with real numbers (not in N and C)?

I can only plot the Gammafunction in the complex plane by using the following:

with(plots);

f:=z->GAMMA(z);

complexplot3d(f);

Is it also possible to plot the Betafunction B(a,b):=int(t^(a-1)*(1-t)^(b-1),t=0..1) in such a way that I can assign special values to a and b?

These solutions will help me so much....Thank you for your answer!!!

For example, the simple pendulum length changes by the law

l = l_0+a*t

where a - constant, t - time, l_0 - link length at t=0.

How it is possible to model such system? Is it possibly to change r_XYZ in Rigid Body Frame under this law or it is necessary to go by another way?

Hi,

I have got few quick questions once i have gone through the features of MapleSim connector and here are they.

• Can we use the S-function created by MapleSim with Targetlink
• If I am doing the HIL simulations, how does MapleSim take care of solvers. Do we need to write the device drivers and tlc files or the tool takes care of it.
• How do I go about doing HIL simulations if my model is discrete.

Would appreciate if...

I often run into this problem. Say I have defined a new variable in terms of some old variables:

     Eq1 := NewVar = OldVar1 + OldVar2

Then suppose I have an expression in terms of the old variables:

     Eq2 := OldVar6 * OldVar5 = OldVar3 * (OldVar1 + OldVar2)

If I want to substitute Eq1 into Eq2 I have to either type

     subs(OldVar1 + OldVar2 = NewVar1, Eq2)

or I can do this

Hi,
I need your help for this problem, please.

$\mathop  {\sum {...\sum }}\limits_{z_r \in {Q_{2}^{*}}}$ such that

$Q_{2}^{*}=((z_1,...,z_r):z_{j}=0,1,\sum_{j=1}^{r}z_{j}=\ell)$, where $\ell = 0, 1, . . . , r$.

For example. If r=3, $\ell=1$; then we are looking for triples with elements 0's or 1's and sum to 1 i.e. $Q_{2}^{*}={(0,0,1),(0,1,0),(1,0,0)}$. So we would like to sum over theses $z_r$'s.

I appreciate your help.

Hi

I have this

diff(q^2*l(a, q)^(1/2)*((1-l(a, q))/(1.1))^(1/2)+(1-a)*(1-q*l(a, q)^(1/2))*q*((1-l(a, q))/(1.1))^(1/2)+a*(1-q*((1-l(a, q))/(1.1))^(1/2))*q*l(a, q)^(1/2), a)

where l(a,q) signifies that l is function of a and q, specifically

RootOf((330578512439669421489*sqrt(1-a)*q^2*sqrt(a)-330578512439669421489*sqrt(1-a)*q^2-330578512439669421489*sqrt(a)*q^2+330578512439669421489*q^2)*_Z^4+(-165289256228925619836*q-165289256228925619836*sqrt(1-a...

Can someone please help me to understand if what follows are four separate solutions.  And if they are, could you also help me to understand what they actually mean.  I  don't understand the 'RootOf' in them.

w1 = RootOf(( v1^2+v2^2+v3^2)_Z^2-1,label=_L3) w*v1,

w2= RootOf((v1^2+v2^2+v3^2)_Z^2-1,label=_L3)w*v2,   

w3= RootOf((v1^2+v2^2+v3^2)_Z^2-1,label=_L3)w*v3,   

b= RootOf((v1^2+v2^2+v3^2...

My first equation is a vector equation which results in three separate equations and four unknowns:

W x V - [( A / |A|)* |W|*|V|*sqrt( 1 - b^2 * (|W|^2/|V|^2)] =0

Where W,V, and A are all vectors with three components.  The four unknowns are w[1], w[2], w[3], and also b.

The other equation i have is that w[1]^2 + w[2]^2 + w[3]^2 = |w|^2, where i know |w|^2.

This makes four equations and four unknowns.

I know v[1],v[2],v[3],a[1],a[2],a[3] and |w|.

Is it possible to switch between worksheet mode and document mode? If yes, how?

Hello everybody,

Consider I have a plane equation: x^2+y^2 + z^2=8

Or every formula of hyperboloid, or another similar equation.

I want you to explain me how to convert from plugged form to the interpreted form and to parametric form such equations.

Please show me an example, as you know every plane equation can be parametric, interpreted and plugged.

Hope you understand what do I mean, 3 types of presentations of the plane equation.

I want to compute expected utilities, i.e. I have a random variable and a utility function, e.g.

with(Statistics);

X:=RandomVariable(Normal(mu,sigma));

u:=t->1-exp(-phi*t);

and now I want to compute the expected utility, i.e.:
