Dear Sir/Madam:
I have the following simultaneous equations to get the 4 unknow variables
by maple engine. However, the maple did not give me anything. Actually,
the exact solutions exist in the educational text. Now, I am trying to get them
on maple. Why it does not work at all?
Please let me know how to do.
Thanks in advance.
restart;
eq1:=A2*t2*exp(zt*t2*om)*sin(t2*wd)+A3*t3*sin(t3*wd)*exp(zt*t3*om) = 0:
eq2:=A2*t2*exp(zt*t2*om...
Dear Sir:
I have the below sum equation.
Please make some correction to get a solution.
with(student);
v:=(w[j])->sqrt(Sum(A[i]*cos(w[j]*t[i]),i=1..n)^(2)+Sum(A[i]*sin(w[j]*t[i]),i=1..n)^(2));
v(w[j]); diff(v(w[j]), w[j]);
value(%);
Thanks
Dear Sir:
I am still a novice to use the maple. Please give some advice for the
following code. Expecially, I try to construct the final P(3x3) matrix.
In the for-loop, normalized vectors are generated. Then, those are
converted into a matrix. But, I do not know how to write a code.

with(LinearAlgebra):
interface(displayprecision=4):
mass:=Matrix([[m[1],0,0],[0,m[2],0],[0,0,m[3]]]);
stif:=Matrix([[k[1]+k[2],-k[1],0],[-k[1],k[1]+k[2],-k[2]],[0,-k[2],k[2]]]);
m[1],m[2],m[3],k[1],k[2],k[3]:=4,4,4,4,4,4;
msri:=simplify(MatrixFunction(mass,sqrt(x),x)^(-1));
mass2:=msri.mass.msri; stif2:=msri.stif.msri;
