Changing The Subject Of A Formula

This video tutorial teaches how to change the subject of a formula, a key algebraic skill. It covers using opposites like addition and subtraction, multiplication and division, and squaring and square rooting to rearrange formulas. The tutorial includes examples, such as solving for W and using Pi, and emphasizes keeping equations balanced. Viewers are encouraged to practice and apply these techniques.

What is the primary goal when changing the subject of a formula?

• To eliminate all variables

• To simplify the equation to a single number

• To isolate a different variable

• To make the equation more complex

When changing the subject of a formula, what should you do to both sides of the equation?

• Subtract the variable

• Perform the same operation

• Multiply by zero

• Add the same number

In the example provided, what is the first step to isolate W?

• Subtract 2L from both sides

• Add 2L to both sides

• Multiply both sides by 2

• Divide both sides by W

How should you treat constants like π when changing the subject of a formula?

• Replace them with zero

• Consider them as numbers

• Treat them as variables

• Ignore them completely

What advanced technique is mentioned for changing the subject of a formula?

• Graphing

• Factorization

• Differentiation

• Integration
