Understanding Tangent and Angle Relationships

The video explores the concept of tangent in trigonometry, focusing on its relationship with sine and cosine. It explains how the tangent of an angle is the slope of the terminal ray and examines the properties of tangent for angles like theta plus pi, negative theta, and pi minus theta. The video highlights the symmetry in the unit circle and how these properties can be useful in solving trigonometric problems and proving identities.

What is the tangent of an angle defined as in terms of sine and cosine?

• Cosine minus sine

• Sine times cosine

• Sine over cosine

• Cosine over sine
