What is the division property for trigonometric expressions

The video tutorial explains the division property, which states that a number or expression divided by itself equals one. This concept is applied to numbers, polynomials, and trigonometric functions. The tutorial provides examples, such as dividing identical expressions, and emphasizes the importance of simplifying expressions through factoring and other operations to apply the division property effectively. The video concludes with practice problems to reinforce the concepts learned.

What is the result when a number is divided by itself?

• 0

• 1

• The number itself

• Infinity

How does the division property apply to polynomials?

• It results in infinity

• It results in one

• It results in the polynomial itself

• It results in zero

What is the simplified form of sine(x) * cosine(x) / sine(x)?

• cosine(x)

• 0

• 1

• sine(x)

Which operation is often necessary to simplify expressions before applying the division property?

• Addition

• Subtraction

• Multiplication

• Factoring

What is the result of 1 + 2 sine(x) divided by itself?

• 2 sine(x)

• 1 / (1 - sine(x))

• 0
