Learn how to verify a trigonometric identity by distributive property

The video tutorial explains how to approach a mathematical problem by setting up the left and right sides, choosing the appropriate side for applying operations, and using identities to simplify expressions. The instructor emphasizes the importance of grouping identities and rewriting expressions in terms of sines and cosines to achieve simplification. The session concludes with a review and practice of the operations discussed.

Which side does the teacher choose to apply multiplication in the trigonometric expression?

• Both sides

• The left side

• The right side

• Neither side

What type of identities does the teacher decide to use for simplification?

• Pythagorean identities

• Double angle identities

• Reciprocal and quotient identities

• Sum and difference identities

Why does the teacher suggest rewriting expressions in terms of sines and cosines?

• To avoid using identities

• To make it more complex

• To simplify the expression

• To make the expression longer

What is the result of rewriting the expression in terms of sines and cosines?

• It equals the left side

• It remains unchanged

• It equals the right side

• It becomes more complex

What is the main focus of the class period according to the teacher?

• Learning new identities

• Practicing applying operations

• Memorizing formulas

• Solving equations
