The video tutorial introduces iteration as a method for solving equations by finding approximate solutions through repeated cycles. It explains the iterative process, where the output of one cycle becomes the input for the next, until the input and output match. The tutorial demonstrates how to derive and apply the iteration formula, using examples to illustrate the process. It concludes with a practice exercise and encourages viewers to engage with the content.

What is the main purpose of using iteration in solving equations?

• To avoid using any mathematical formulas

• To solve equations without any calculations

• To find an exact solution quickly

How is the iteration formula typically derived?

• By eliminating all variables from the equation

• By multiplying all terms by a common factor

• By rearranging the equation to make the highest power of X the subject

• By adding a constant to both sides of the equation
