We found 300 resources with the concept cosine
3 mins 10th - 12th CCSS: Adaptable
New ReviewDon't go off on a tangent. An instructive video describes how to find the sine, cosine, and tangent ratios of an angle in a right angle. It describes how to label the sides of a right triangle and how to use mnemonics to remember the...
Module 4: Similarity and Right Triangle Trigonometry
9th - 12th CCSS: Designed
New ReviewRight you are to use a great resource. Starting with a lesson on dilations, scholars learn about similarity transformations and similar triangles. They use the knowledge to develop an understanding of right triangle trigonometry in later...
Module 6: Modeling Periodic Behavior
10th - 12th CCSS: Designed
New ReviewAround and around we go ... again, and again, and again, and again! That's the nature of a periodic function. Young scholars learn how to model a periodic pattern with trigonometric functions. The nine-lesson unit explores the connection...
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.
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,...
Derivatives of Trigonometric Functions: Derivative of sin(x)
11th - Higher Ed
Graphically find the derivative of sin(x). Using the interactive, pupils graph the slope of the tangent line to the sine function. Class members use the resulting graph to determine the derivative of the sine function. They verify their...
