Verify an identity by converting to a monomial denominator

The video tutorial demonstrates how to verify a trigonometric identity by choosing which side to simplify, focusing on converting expressions to monomial denominators, and using Pythagorean identities. The process involves multiplying by conjugates, simplifying using trigonometric identities, and rewriting expressions in terms of sine and cosine to achieve equivalence.

What is the first step in simplifying a trigonometric identity with rational expressions on both sides?

• Multiply by the conjugate

• Use Pythagorean identities

• Choose the side with a monomial denominator

• Convert all terms to sine and cosine

When simplifying an expression using the difference of squares, what is the result of multiplying the conjugate?

• A monomial expression

• A difference of two squares

• A binomial expression

• A sum of two squares

Which identity relates cotangent squared and cosecant squared?

• cotangent squared = 1 + cosecant squared

• cotangent squared = 1 - cosecant squared

• cotangent squared = cosecant squared - 1

• cotangent squared = cosecant squared + 1

What is the final form of the expression when rewritten in terms of sine and cosine?

• 1 + sine of Theta over cosine of Theta

• 1 + cosine of Theta over sine of Theta

• sine of Theta over 1 + cosine of Theta

• cosine of Theta over 1 + sine of Theta

How do you combine terms with a common denominator in trigonometric expressions?

• Divide the numerators and keep the denominator

• Subtract the numerators and keep the denominator

• Multiply the numerators and denominators

• Add the numerators and keep the denominator
