I want to sovle two equations with two variablesδ,Δ numerically. So I tried to use ode45 but I didnt find anyone have the problem that second order of two variables are in one equation. This is a simpified version of the equation. M*(d^2δ/dt^2+d^2Δ/dt^2)=2δ+1...
I am trying to make the following code to solve the unknow variables (x(1) , x(2)) at different temperatures (T). I could solve the system using fsolve function only when I entered the T value manuly in the funtion Psat_f. However, I want...
Write out the two equations that have the two variables you want to solve. For this example, we will find the value for "x" and "y" in the two equations "3x + y = 2" and "x + 5y = 20" Step 2 Solve for one of the variables in on one of the equations. For this example, ...
Hello, I'm trying to solve four differential equations. Each differential equation has two variables a and b (not x). My goal is finding out the values of variables( a and b) when [sum of four equations] is minimum using fmincon. The ranges for a an...
How to solve the equations with two variables? Solve these three equations for y_1, y_2, y_3 , in terms of B_1, B_2, B_3 : Solve the equation: 4 3 N = 43 N = ___ Provide steps. How to solve an equation with two variables? How...
This is an arithmetic sequence with two variables, _xn_ and n. If you know one, you can find the other. For example, if you're looking for the 100th term (x100), then n = 100 and the term is 502. On the other hand, if you want to know which ...
your problem well enough to be solvable. As of now you have told us that you have 4 coupled ODEs, where one coefficient will depend on the final solution. (This oviously breaks the causality of physics, and mathematically it doesn't make much sens...

|1 - 4k| is greater than or equal to -11 How do you solve the absolute value inequality: |3x - 3| is strictly less than -15 Solve the inequality. absolute of (x + 1) greater than or equal to 3. How do you solve inequalities with two variables? Solve the following absolute...
I've got this two equations. ThemeCopy dz/dt = A*z + B*y - C*(dy/dt) dy/dt = H*y + F*z - E*(dz/dt) I would aprecciate If you could help me to solve this. I've tipped this in Matlab after looking at some questions, related to mine. This is...
