This is a replacement unit to facilitate the teaching and learning of right-angle triangle trigonometry. The students begin by ‘learning’ how to sail a boat and then engage with various aspects of sailing and as a result learn about the fundamental trigonometric ratios. The unit comes with pre-made 9860 Geometry files that enable the students to sail virtual boats, collect data on their sailing and through this learn about trigonometric ratios. The unit includes traditional learning and problems as well as some not so traditional learning.
This document presents an approach or approaches to the 2011 WACE Mathematics 3C3D Examination. These approaches incorporate the use of CAS as well as ‘by hand’ solution methods. At times two alternative methods are presented. The providing of two solutions is intended to encourage a conversation between teachers and students about the most deserning and efficient way to tackle the mathematics presented in this form of assessment.
How to update the operating system of your hand-held ClassPad using a Windows PC.
How to download programs, eActivities, csv files, pictures and so on into your handheld ClassPad from a Mac or Windows computer.
Collect like terms and expand and simplify expressions such as 3(4-2x)^2.
Use the sequence function in Main to find the defining rule for various sequences
Eliminate one variable from an equation using another equation.
Example: If x=8-2t and y=6t-1 find an expression for y in terms of x.
Create your own user functions.
Examples (i) f(x)=1/x or (ii) Ckh2ms to convert speeds from km/h to m/s
Managing your own user defined functions such as those created in the previous topic.
Create and use a function with many variables. Also edit a user defined function in the program editor.
