Evaluate special trigonometric limits using algebra

The video tutorial covers the process of factoring expressions and applying limits. It begins with an introduction to identifying common factors and proceeds to demonstrate how limits are applied in the context of factoring. The tutorial includes a detailed step-by-step calculation of limits, followed by a conclusion and reflection on the lesson.

What is the first step recommended when you encounter a potentially factorable expression?

• Convert it to a decimal

• Use a calculator to solve it

• Try to factor out a common factor

• Ignore it and move on

What is the significance of factoring out a common factor in an expression?

• It has no effect on the expression

• It helps in simplifying the expression

• It changes the value of the expression

• It makes the expression more complex

When evaluating limits, what is the expression simplified to as X approaches zero?

• Negative one

• One

• Zero

• Infinity

What is the result of the expression after applying the limit as X approaches zero?

• Two

• Negative one

• One

• Zero

What is the final result of the expression after simplification?

• Negative one

• Two

• One

• Zero
