## How can we put restrictions of dependenc...

Maple 15

Hi to All!

I have an equation including 6 parameters; k_1, k_2, k_3, l_1, l_2, l_3 and a constant a_1. I want to solve this equation for l_1, l_2, and l_3. I get a solution as can be seen in the link but I wonder if there is a solution such that l_j is written in terms of k_j and a_1, j=1,2,3. I mean can be put a restriction on a parameter such that it depends to specific parameters?

Regards,

## How do I solve a huge expression for par...

Maple 15

Hi to All! I have a big expression including 10 constant parameters (k_1, k_2, k_3, omega_1, omega_2, omega_3, a_3, b_2, c_0, c_2) to be solved for a_3, b_2, c_0, c_2. I wonder if there is any relation between the constants a_3, b_2, c_0, c_2 not depending on (k_1, k_2, k_3, omega_1, omega_2, omega_3) satisfying this big expression e.g. a_3=2, b_2=c_0/5, c_2 free.

I also tried fsolve but I could not get an answer.

Maple 13

Hi everyone!

Is it possible to evaluate int(diff(u(x,y,t),x)*v(x,y,t)+diff(v(x,y,t),x)*u(x,y,t),x) directly as u(x,y,t)*v(x,y,t) in Maple?

Thanks.

## extracting coefficients of exponential f...

Maple 13

Consider for instance the following equation:

Eq:=(a-4)*exp(4*x)+(b+1)*exp(2*x)+(c-2)=0

How can I list the coefficients of the exponential functions and also solve the equation for the constant parameters

a, b, and c?

I tried

[coeffs(collect(lhs(EQ), exp), exp)] =~ 0;

but it did not work. Thank you for your help.

## How do I check that a function of two va...

Maple

Hi,

Is there a way of determining whether a function of two variables is continuous or not? Can we find the discontinuity points

of such multivariable functions? (Considering the graphs of the function is not always helpful.)
