Hi there,

I used the implicitplot command to plot an implicit equation as follows:

with(plots):

implicitplot(x^3+y^3-3xy=0,x=-3..3,y=-3..3, scaling=constrained)

but maple13 takes error and specifies {xy} as an extra unknown.

Your help will be appreciated.

Regards

AoA. How are you hope you will be fine. Sir the following matrix have been given

A := Matrix(2, 2, {(1, 1) = 1, (1, 2) = 2, (2, 1) = -1, (2, 2) = 2});

B := Matrix(2, 2, {(1, 1) = 1, (1, 2) = 0, (2, 1) = -2, (2, 2) = 3});

C := Matrix(2, 2, {(1, 1) = 0, (1, 2) = 0, (2, 1) = 0, (2, 2) = 0});

I want to write M by M matrix using the above matrices like this

P:=[[[A,B,B,...,B],[C,A,B,...,B],[C,C,A,...,B],[.,.,.,...,B],[C,C,C,...,A]]]

AoA... I want to plot the following functions

f(x)=sin(x)

g(x)=sin(x)-x+x^2

h(x)=cos(x)-sin(x)

I(x)=exp(x)-x

J(x)=sin(x)+exp(x)

in one coordinate having the line style and legend like attached file.

AoA. How are you? I want to solve the following equation in one step and convenient way please help

 

psi(x):=Matrix(1,3,[x,x-1,x^(2)-x-1])

P := Matrix(3, 3, [1, 2, 1, 0, 1, 1, -1, 2, 3])

U := Matrix(3, 3, [a[1, 1], a[1, 2], a[1, 3], a[2, 1], a[2, 2], a[2, 3], a[3, 1], a[3, 2], a[3, 3]])

u := psi(x)^T*(P^2)^T*U*P^2*psi(t)-t*psi(x)^T*(P^2)^T*U*P^2*psi(1)-x*psi(1)^T*(P^2)^T*U*P^2*psi(t)+t*x*psi(1)^T*(P^2)^T*U*P^2*psi(1)

 

If you reduce my computational work or have any suggestion to solve please give.

AoA. How are you? Hope you will be fine. I want write the following in Loop for any M

 

F[r,s]:=2^(k+2) m sqrt((c[r-1])/(c[s-1])) for r=2...(M+1), s=1..r-1 and (r+s)=odd;

F[r,s]:=0  otherwise

 

 

Aslam-u-Alikum, want to write the following in Maple please help

psi[1]:=psi[1,0];

psi[2]:=psi[1,1];

psi[3]:=psi[1,2];

psi[4]:=psi[1,3];

psi[5]:=psi[2,0];

psi[6]:=psi[2,1];

psi[7]:=psi[2,2];

psi[8]:=psi[2,3];

AOA... How are you all. I need the answer of the following question.

 

input in Maple: expand(exp(a+b)+exp(c+b))

output:  exp(a)*exp(b)+exp(c)*exp(b)

and

input in Maple: expand(exp(2a+b)+exp(3c+b))

output:  (exp(a))^2*exp(b)+(exp(c))^3*exp(b)

but i need exp(2a)*exp(b)+exp(3c)*exp(b)

This Maple 13 so maybe things have been fixed. Here are four points whose convex hull consists of three points. Sometimes the result comes out correct, more often it does not. With numbers this small it shouldn't be an issue of roundoff. But changing digits changes the result!

 If I want to plot Smith Chart ,how do I mark a circle of arbitrary values?

then,How do I avoid the polar line to cover other  circle line?

Any body can give me some ideas or better ways to plot Smith Chart?

Thanks.

i'm going to solve the two eq. and plot the answer point

i try to do two group but the first succeed the second get some wrong

the first i named 1 ,and second named 2 as below

the 1 plot the correct point that i want

Although the 2 solve eq too but it didn't plot the point on(-0.36,0.29),

the code of this two is same ,

anyone can help me?
