## plot3d ...

Maple

I do an order as follows,

> restart;

## eliminate&plot...

Maple

I use eliminate to get a relation of two independent variables,and then I want to use plot to draw a picture of the two independene variable,such as

eliminate({L[A]+L[DD], S[A]+S[DD]}, kk)

and I got the relationship of kk&w,I want to draw the relationship,maybe plot can not do it ,what others I can do?

thank you

## collect(S,(b-a))...

Maple

I want to get a common divisor from multinomial,such as (b-a), can I use the order collect (S,(b-a)),maybe it is wrong,what others I can use?

thank you

## eliminate...

Maple

I used eliminate,but there is no result,no error.

I donot know why,what shoud I do?

The programme is in the attachment,the last expression is the eliminate.How should I correct it?

Thank you

## the figer in&out parentheses...

Maple

After multipication,I got some [  ],like these

(1.388888889*10^(-7)*omega^4+3.429355280*10^50-1.000000000*10^(-36)*omega^6-1.543209877*10^22*omega^2)*bbbb^3+(1.924500898*10^5*omega^2*[-5.702224882*10^14*bbbb]+[4.064421073*10^48*bbbb]+1.666666666*10^5*omega^2*[-3.292181070*10^14*bbbb]-2.000000000*10^(-24)*[-3.292181070*10^14*bbbb]*omega^4)*bbbb^2+(2.777777776*10^16*[-5.702224882*10^14*bbbb]^2-1.000000000*10^(-12)*omega^2*[-5.702224882*10^14*bbbb]^2-1.000000000*10^(-12)*omega^2*[-3.292181070*10^14*bbbb]^2+2.777777776*10^16*[-3.292181070*10^14*bbbb]^2)*bbbb
