Pythagorean Proofs
In this activity, students will explore proofs of the Pythagorean Theorem. Students will explore the proof of the Pythagorean Theorem using area of squares, area of triangles and trapezoids, and by dissection. Students will then be asked to apply what they have learned about the Pythagorean Theorem.https://education.ti.com/en/activity/detail/pythagorean-proofs_1
Parametrizing the Unit Circle
The purpose of this activity is to use parametric equations to "unwrap" the unit circle. This process will allow students to obtain the graph of the function y = sin(x).https://education.ti.com/en/activity/detail/parametrizing-the-unit-circle
