EagleCat: trig-G

Explore the graphs of trigonometric equations in the form: (a) y = a sin[n(x - h)] + k, (b) y = a cos[n(x - h)] + k and (c) y = a tan[n(x - h)] + k. Use sliders or enter values to dilate, reflect and translate the basic trigonometric equations y = sin(x), y = cos(x) and y = tan(x), and observe the changes in the amplitude, ...


Simple harmonic motion

This collection of six digital curriculum resources includes resources that develop the theoretical and practical aspects of simple harmonic motion (SHM). Video sequences illustrate the fundamental kinematic principles of SHM and reference web pages provide background material on the mathematical techniques required, including ...

Simple harmonic motion

Use your knowledge of calculus and circular motion to analyse back-and-forth motion. Discover how the position, velocity and acceleration vary, but are closely related. Learn how to apply the theory to vibrating objects such as pendulums and loudspeakers. This resource consists of a video in four sections with a supporting ...


Graphing functions

This collection contains five digital curriculum resources (all interactive learning objects) that introduce students to graphing linear, parabolic, cubic and trigonometric functions. Through exercises, students investigate how the constants in each function equation influence relevant aspects of graphing, such as dilations ...
