Verifying trigonometric identities by converting to sines and cosines

What is the first step in simplifying a trigonometric equation according to the video?

• Identify the more complex side to work on.

• Start with the side that has fewer terms.

• Find the simpler side to work on.

• Convert all terms to tangent and cotangent.

When trying to make one side of an equation look like the other, what operation is often necessary?

• Subtraction

• Division

• Exponentiation

• Addition

Why can't tangent and cotangent be combined directly?

• They have different coefficients.

• They are both odd functions.

• They are both even functions.

• They are not like terms.

What is the recommended method for dealing with trigonometric functions in an equation?

• Convert them to exponential form.

• Convert them to sines and cosines.

• Convert them to tangent and cotangent.

• Convert them to secant and cosecant.

Which identity is used to simplify expressions involving sine squared and cosine squared?

• Reciprocal identity

• Pythagorean identity

• Double angle identity

• Sum of angles identity
