Math Portfolio Assignment Type 2 Investigating the Graphs of Sine Function The task of this assignment is to investigate various sine graphs and recognise patterns and generalisations. Part 1 Look at the graph of y = sin x. Compare the graphs of y = 2 sin x ; y = 1/3 sin x ; y = 5 sin x. Investigate other graphs of the type y = A sin x. How does the shape of the graph vary as A varies? Express your conjecture in terms of a) transformation(s) of the standard curve y = sin x. b) characteristic(s) of the wave form. To do the graphs including graph y = sin x, first I used my TI-83 Graph Calculator to have an idea of how the sketch should look. Then, for the real graph I used in the computer, a program called "Omnigraph" that is ideal for drawing graphs in the Cartesian set of axis, and that could be...
