The document describes three trigonometric functions with periods of 2 and amplitudes of 300 or -300. The first function is y=sinx. The second is y=2sin(4x+300)+5, and the third is y=2sin(4x-300)+5. A table is given showing the values of x, y, y^2, and y^3 for values of x from -30 to 30. The document was presented by Mary Barrera.
