First solve the diffrerential equation and obtain function P as function of t and k using dsolve 테마복사 syms p(t) pm k lambda lambda = 0.03; pm = 9000; eqn = diff(p,t) == lambda*p*(1-p/pm)-k cond = p(0) == 5000; P(t) = dsolve(eqn,cond); Solve the equation...
Expressions: Expressions are mathematical phrases composed of variables, constants, and operations. Evaluation: It is the process of calculating the value of an expression or equation. Equality is the link that connects expressions and evaluation. It enables us to solve equations, determine variable va...
and being able to identify which one your particular problem falls into will tell you how exactly to approach it. An obvious sign of the math problem being algebraic is a use of variables, whereas an obvious sign of it being geometric in nature is a use of graphs....
Hello, I was trying to solve a algebraic equation, e.g.: symsa b c d [c,d]=solve(2*a-b,2*b-a+3,'a','b') OnMatlab 2017b, I can get the final results with the alert:Do not specify equations and variables as character vectors. Instead, create symbolic variables with syms....
You have to specify 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 do...
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. ...
