Applications of Trigonometry

Parametric equations are treated in this unit, including an application to parametric projectile motion. Polar coordinates and equations and the use of trigonometry in the geometric interpretations of complex numbers.

Precalculus: Applications of Trigonometry Activities

Title
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). Standards \| Textbook	2058	9
Parametric Symmetry The purpose of this activity is to build a tns document that can be used to investigate reflections and symmetries of curves defined parametrically. Standards \| Textbook	1968	9
Parametric Ball Toss This lesson involves determining the height of a ball at a given time and determining the time at which the ball is at a certain height. Standards \| Textbook	2028	11
Parametric Projectile Motion Students will understand how changing the initial velocity and the initial angle change the path of a projectile. Students will be able to write the parametric equations for the path of a projectile. Standards \| Textbook	23	0
Two Models are Better than One This lesson involves modeling the amount of carbon dioxide in the air over a 12-month period. Standards \| Textbook	1980	10
Polar Coordinates This lesson involves a brief introduction to the polar coordinate system. Standards \| Textbook	2089	9
Rose Curve This lesson involves clicking on sliders to observe the effect of changing the values of a and n in the equation r = asin(nθ). Standards \| Textbook	2457	12
Complex Number Addition This lesson involves the addition of two complex numbers. Standards \| Textbook	2081	9
Complex Number Multiplication This lesson involves the product of complex numbers, powers of i and complex conjugates. Standards \| Textbook	2081	10
Sinusoidal Modeling This lesson involves writing an equation to predict the average monthly temperature for a certain location based on past data. Standards \| Textbook	2113	10
