How can we put restrictions of dependency on the solutions of an algebraic equation?

guras — Mon, 17 Jul 2023 13:37:35 Z

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?

Thank you in advance.

How do I solve a huge expression for parameters depending on particular constants?

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.

Thank you in advance.

How to slove this equation in Maple (get the optimal w), where y is a vector R(n*1), X is a matrix R(n*m), and w is a vector R(m*1),lambda is a scalar.

How to remove the ln(e) in the fianl answer shown in the picture, ( must be Maple 15), thanks

Numerical evaluation of the Zeta function

Heinrich — Mon, 14 Jun 2021 11:32:58 Z

Hello everybody – It looks like there is a bug in the numerical evaluation of (multiple) Zeta function. Take for instance, Zeta(3, 0.5) which is approximately 8.4144. Maple gives approximaterly -96.0033. Is there a bug somewhere?

Thank you

Maximum value of a function

Hi Users!

Hope everyone is fine here. I want to find the values of M and L for any functions f(x,y) and y(x) such that

abs(diff(f, y)) for all a ≤ x ≤ b, -∞ < y < ∞ and

abs(diff(y, x, x, x)) for all a ≤ x ≤ b, -∞ < y < ∞

For example for

f:=y-x^(2)+1; 0 ≤ x ≤ 2, -∞ < y < ∞ and

y:=(x+1)^2-.5*exp(x); 0 ≤ x ≤ 2, -∞ < y < ∞

the values of L = 1 and M = 0.5exp(2)
