What does it mean to solve a difference equation?

This means you are searching for a function f(x) such its first-order derivative will be equal to the function itself. Once your search for such a function is over, you have solved the differential equation!! Here is another example: f(x)=f ''(x)

Can Photomath do differential equations?

if you're stuck on a differential equation, you can use apps like Photomath to help you solve it. You take a picture of the equation and it will tell you the answer. It also shows you step by step how to solve the equation.

How do you solve a difference equation in Matlab?

Represent the derivative by creating the symbolic function Dy = diff(y) and then define the condition using Dy(0)==0 . syms y(x) Dy = diff(y); ode = diff(y,x,2) == cos(2*x)-y; cond1 = y(0) == 1; cond2 = Dy(0) == 0; Solve ode for y . Simplify the solution using the simplify function.
