Activity Overview
In this activity, students use the CellSheet™ Application to graph vectors. They also learn to find the sum of two vectors.
Before the Activity
Install the CellSheet on the calculator using the TI Connect™, TI-Connectivity cable, and Unit to Unit cables
See the attached PDF file for detailed instructions for this activity
Print pages 75 - 84 from the attached PDF file for your class
During the Activity
Distribute the pages to your class.
Follow the Activity procedures:
Open the CellSheet Application on the calculator and start a new spreadsheet
Convert the polar coordinates of the two vectors to the x and y vector coordinates
Graph the vectors
Write the two vectors in their rectangular form in terms of x and y
Add the two ordered pairs to obtain the sum
Graph the resultant vector
Connect the end points of the vectors and the resultant
Observe the resultant vector is the diagonal of the parallelogram having sides defined by the magnitude and direction of the 2 vectors
After the Activity
Students will complete the worksheet and answer questions.
Review student results:
As a class, discuss questions that appeared to be more challenging
Re-teach concepts as necessary
