It is rare to solve differential equations because they can be extremely complex and often have no analytical solution, requiring numerical methods and approximation techniques.
So let us take a deeper look
Differential equations are mathematical equations that involve an unknown function and its derivatives. They are used to describe various physical phenomena in the fields of physics, engineering, biology, and economics, to name a few. However, solving differential equations is known to be notoriously difficult and timeconsuming because they can be extremely complex and often have no analytical solution, requiring numerical methods and approximation techniques.
According to Carl Friedrich Gauss, “Mathematics is the queen of sciences, and number theory is the queen of mathematics.” However, when it comes to solving differential equations, the situation is not as straightforward since there are many challenges that arise. Some of these challenges include the following:

Nonlinearities: Many physical systems involve nonlinear equations, which are difficult to solve analytically.

Boundary conditions: In many cases, differential equations are solved subject to certain boundary conditions. Finding these boundary conditions can be tricky, and some problems may have no unique solution.

Dimensionality: Some differential equations involve multiple variables, making them challenging to solve analytically.

Numerical Instability: Numerical methods of solving differential equations can become unstable if not done correctly.

Approximation Errors: Approximating continuous solutions with discrete representations can lead to errors, which can accumulate and become significant over time.
Despite these challenges, differential equations are still widely used because they can provide insights into the behavior of physical systems that are difficult or impossible to obtain experimentally. In summary, as Richard Feynman once said, “Nature uses only the longest threads to weave her patterns, so that each small piece of her fabric reveals the organization of the entire tapestry.” Differential equations provide one of those threads, allowing us to understand the organization of the physical world.

Why are differential equations important?
In applications, the functions generally represent physical quantities, the derivatives represent their rates of change, and the differential equation defines a relationship between the two. Such relations are common; therefore, differential equations play a prominent role in many disciplines including engineering, physics, economics, and biology .
