Segments Formed by Intersectiong Chords, Secants, and Tangents
Learners investigate the properties of segments formed which chords, secants, and tangents, intersect. The dynamic nature of Cabri Jr. allows students to form and verify conjectures regarding segment relationships.

Chors, Secants, Tangents
Students identify the relationship between chords, secants and circles. In this geometry lesson plan, students calculate the length of the chords. They sketch the secant lines on a circle.

Integrals with Even Powers of Secant and Tangent
Learners integrate integrals that involve even powers of tangents and secants. They work several problems that require the use of integration, and the identity tan^2x+1=sec^2x. Students use integration by parts for the first integral....
