This short video shows how to determine a derivative value, i.e. the value of a derivative function for a given x value, using the Run.Mat app of a CASIO fx-CG series graphics calculator. CG20 AU and CG50 AU versions presented.
This short video shows how to define and calculate with matrices using the Run-Matrix app of a CASIO fx-CG series graphics calculator. CG20 AU and CG50 AU versions presented.
This short video shows you how to find the area of a region between two graphs using the Graph app of a CASIO fx-CG series graphics calculator. CG20 AU and CG50 AU versions presented.
This short video shows you how to transfer memory content between the Main and Storage Memory of a CASIO fx-CG series graphics calculator. CG20 AU and CG50 AU versions presented.
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.
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 and use a function with many variables. Also edit a user defined function in the program editor.
Draw a line segment between two points A and B and construct its midpoint.
Solve simultaneously the equations 3y – 2x = 5 and x + 2y – 8 = 0 graphically using both Main and Graph windows.
