Slide the values of a, b, c and d to observe the changes of graph f (x) = a sin (bx + c) + d. What can you say about the effects of these values towards the function sin (x)?

Sine Function
A sine function generally can be written as f (x) = a sin (bx + c) + d. Try to move point A in the graph below, point B is the recurring point after one cycle. The period of the cycle is 
units and the amplitude is a units.
