Converting to sines and cosines to verify my trig identity

The video tutorial explains how to verify a trigonometric identity by simplifying the expression on the left-hand side. The instructor converts all terms to sines and cosines, simplifies the expression, and demonstrates that it equals the right-hand side, thus verifying the identity.

What is the initial strategy suggested by the teacher to simplify the left-hand side of the equation?

• Apply the double angle formula

• Use the Pythagorean identity

• Pair trigonometric functions with their reciprocals

• Convert all terms to tangent and cotangent

Which identity is used to simplify the expression by canceling out terms?

• Pythagorean identity

• Double angle identity

• Quotient identity

• Reciprocal identity

What is the main technique used to simplify the trigonometric expression in the second section?

• Factoring the expression

• Converting everything to sines and cosines

• Using the angle sum identity

• Applying the half-angle identity

How does the teacher suggest handling the division of terms like X^2 / X?

• By dividing the exponents

• By adding the exponents

• By multiplying the exponents

• By subtracting the exponents

What is the final result of the simplification process?

• Sine of X plus cosine of X

• 2 sine of X

• 2 cosine of X

• 3 sine of X
