Sample Text:
You will then use the knowledge gained to describe a variation of y = cos x. 1.Consider the following variations y = sin x. y = a sin x, for a = 1, a = 2, a = 4, a = −2 and a = 0.5 Comment on the effect that varying the value of ‘a’ has on the graph and include sample graphs in your report. By observing the graph above, we are able to observe how varying the value of ‘a’ has effected the graph. a is denoted as the amplitude of the graph. The amplitude of the sine function controls the range of the function. Firstly, when observing y = 1 sinx, y = 2 sinx and y = 4 sinx we are able to see that when the amplitude (a) is increased, the greater the ‘stretch’ of the t...

1. Explore variations of Y = sin x using FXGraph. Some or all of the following variations can be considered, choosing appropriate values for a, b, c and d. What pattern of changes have you observed from the above exercises? Summarise these. a) Y = A sin x b) Y = sin (Bx) c) Y = sin (x – C) d) Y = sin x + D e) Any Combinations of the Above Variations: Y = a sin x + d 2. Choose your own sine function and describe how it will differ from y = sin x based on patterns you have observed above. Verify your answer. Own Sine Function: Y = (sin x) / E 3. Will the same patterns apply to variations of Y = cos x? Verify your answer.
