Basic Differential Equation Can you check my work?

In summary, a differential equation is an equation that relates a function to its derivatives and describes how the function changes over time. The purpose of solving a differential equation is to find a function that satisfies the equation and helps us understand the behavior of a system. To solve a basic differential equation, one must isolate the dependent variable, find its derivative, and integrate both sides of the equation using methods such as separation of variables, substitution, or integration by parts. Differential equations have various applications in fields such as physics, engineering, economics, and biology, where they are used to model and analyze systems and processes. While a scientist cannot check specific work on solving a differential equation, there are online resources and tools available to verify solutions and ensure accuracy.

Homework Statement


state the order and linearity of the diff eq[/SIZE]

(d^2u/dr^2)+(du/dr)+(u)=cos(r+u)

1)the order is the second order. since the highest derivative is 2
2) the term cos(r+u) is not linear therefore this equation is not linear.

is my reasoning for 2) right since the dependent variable is contain in cos(r+u) that makes this non-linear, right?
