Trigonometric Ratios: A Geometer's Perspective
9th - 11th CCSS: Adaptable
What do all right triangles have in common? Young mathematicians investigate the trigonometric ratios in relation to right triangles. Their investigations lead to a hypothesis they use to determine unknown lengths in different triangles.
Trigonometric Ratios with a Calculator: Lesson
4 mins 9th - 12th CCSS: Adaptable
Calculators ... they are more efficient than tables. Using two 30-60 right triangles, the segment of a playlist on geometry shows that trigonometric ratios for an angle are the same independent of the size of the triangle. The video...
Inverse Trigonometric Ratios: Lesson
5 mins 9th - 11th CCSS: Adaptable
Finding the inverse of trigonometric ratios is not the same as finding the reciprocal. The presentation introduces how to find the angle of a right triangle given sides. Part of a larger playlist on geometry, the video uses the inverse...
Trigonometry Word Problems: Lesson
3 mins 9th - 11th CCSS: Adaptable
Look up or down to find the answer. A segment of an extensive playlist on geometry introduces angle of depression and elevation to find indirect measurements. Using trigonometric ratios, the presentation finds missing sides and angles...
The Trigonometric Ratios: Lesson
6 mins 9th - 12th CCSS: Adaptable
SOH, what is this thing called trigonometric ratios? A section of an extensive playlist on geometry identifies the adjacent and opposite sides in relationship of an angle. Using the identified sides, the video defines the sine, cosine,...
I Can Determine the Height of a Rocket!
9th - 12th CCSS: Designed
Three, two, one ... blastoff! Individuals use clinometers to measure angles of elevation for tall objects, including a launched rocket if available. Using these measurements, they apply trigonometry to determine the heights of the objects.
EngageNY Algebra II: Module 2
10th - 12th
Building on young mathematicians' prior knowledge of geometry and algebraic functions, this 17-lesson unit introduces the topic of trigonometric ratios. Starting with the basic definitions of sine, cosine, and tangent, students move on to investigate the graphs of these functions and their use in modeling real-world situations.
