# How to Derive Equations From the Nth Order?

If a function f(x) is differentiated, we obtain its derivative, known as f'(x). If this first derivative is further differentiated, we obtain its second derivative, f"(x), and if the second derivat...

## How to Solve Higher Order Linear Equations With LN?

Linear equations, by definition, are equations of the form ax+b=c. As such, linear equations are of order 1, and if they have the term "ln," it exists in regards to the c coefficient only. For inst...

## Why must the rules for the order of operations be understood before solving the equations in this section?

The answer will not be the same if you do not follow the order of operations. PEMDAS is the way most people remember it. It tells you what to do first and you need to know this to do the problems...

## Why is it necessary to study order of operations and laws of operations before you solve equations?

Because if you did operations in an impermissible order, or violated laws of operations, then your solution to the equation is wrong.
