Shooting Arrows through a Hoop
11th - 12th CCSS: Adaptable
New ReviewThe slope makes a difference. Given an equation of a circle and point, scholars determine the relationship of the slope of a line through the point and the number of intersections with the circle. After graphing the relationship, pupils...
Instantaneous Rates of Change
9 mins 8th - 12th CCSS: Adaptable
Here's a great lesson that looks at slope as an instantaneous change. Using an estimated tangent line, the presenter shows the class how to find an approximation for the instantaneous rate of change. Scholars determine the slope of the...
Equation of a Tangent to a Circle
5 mins 8th - 12th CCSS: Adaptable
Don't go off on a tangent—let the video do the talking! A video lesson demonstrates how to write the equation of a line tangent to a circle given the point of tangency and the equation of the circle. The instructor explains both a...
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,...
Basic Trigonometric Limits: Evaluating Limits of tan(x)
11th - Higher Ed
Chase a periodic moving limit. Learners graphically determine the limit of the tangent function at different input values. Using sliders, pupils find out whether the tangent function approaches the same value from the left and the right....
EngageNY Algebra II: Module 2
10th - 12th CCSS: Adaptable
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.
