Verifying a trigonometric Identities

The video tutorial demonstrates how to verify a trigonometric identity involving secant and cosine. It begins by selecting the more complex side of the equation and rewriting cosine in terms of secant. The tutorial then simplifies the expression by eliminating fractions and multiplying by secant. Finally, it shows that the simplified expression equals the original secant, thus verifying the identity.

What is the first step in verifying the trigonometric identity involving secant and cosine?

• Choose the simpler side to work with

• Directly equate both sides

• Convert everything to sine and cosine

• Pick the more complex side to simplify

How is cosine expressed in terms of secant?

• secant + 1

• secant - 1

• 1/secant

• secant * 1

What operation is used to eliminate the fraction in the expression?

• Addition

• Division

• Subtraction

• Multiplication

What happens to the terms secant(Theta) - 1 in the numerator and denominator?

• They add up

• They cancel each other out

• They remain unchanged

• They multiply

What is the final result of the simplification process?

• Theta

• secant of Theta

• cosine of Theta

• 1
