HW 4.3.2 - Graph Sine, Cosine, Tangent For #1-4, find the period and amplitude. 1. 2. y= COS y sin -1- 3. y = = sinox 4. y = = cos- 5. True/False. The graph of the function given by f (x) = sin (x + 2x) translates the graph of f (x) = sinx exactly one period to the right so that the two graphs look identical. For #6-15, sketch the graph on your own graph paper. 6. y = -2tan3x 7. y = -3tannx 8. y = sin4x 9 . y = cos2nx 2nx y = -sin 3 11. y = sin (x - 2n) 12 y = 2cosx - 3 13. y = 3 cos(x + 1) - 3 14. y = 4 cos (x + ") + 4 15. y = -3cos(6x + n)
