Investigating The General Sine Function (in degrees)
This demonstration allows you to manipulate four elements of the general sine function, either separately or in combination, and observe the effects on the graph.
1. Before beginning, make some predictions; what do you think will happen as a, b, c and d vary ? 2. What effect do a, b, c and d have on the shape of the graph? (Consider negative values as well.) 3. Did the changes that you observed match your predictions? 4. Can you explain why these changes in the shape of the graph occur?
