How to prove an identity two different ways

The video tutorial explains how to solve equations by eliminating fractions and using trigonometric identities. It introduces two methods: dividing by cosine and multiplying by secant. The tutorial emphasizes understanding different approaches to problem-solving in trigonometry.

What is the primary focus when trying to simplify an equation with fractions?

• Multiplying by zero

• Adding more terms to the equation

• Creating a fraction on both sides

• Eliminating the fraction

Which trigonometric expression can be used to multiply and simplify the equation in the second method?

• Tangent

• Secant

• Cosine

• Sine

What is the result of multiplying secant with sine over cosine?

• Cosine

• Tangent

• Sine

• Cotangent

What is the identity of secant in terms of cosine?

• 1 over cotangent

• 1 over cosine

• 1 over tangent

• 1 over sine
