Explorations Of Our Digital Future Summer 2006 Lab 2 Warm-Up Worksheet Written by: Jeremy Garrett Part 1: Math Review – Nested Equations Using your engineering graph paper, sketch the following: Precision is not important – you will be grading on position, not the quality of the shapes. Use Radians, and not degrees, for the sine wave functions. Match the following equations to the following graphs. For each question simply respond with A, B, C, D, E, or F (for none of the above) 1) y = x^2 D 2) y = (x^2) + 2 C 3) y = (x+2)^2 A 4) y = sin(x) E 5) y = sin(x+2) B A) B) C) D) E) F) (none of the above) -4 -3.5 -3 -2.5 -2 -1.5 -1 -0.5 0 0.5 1 1.5 2 2.5 3 3.5 4 -16 -12 -8 -4 0 4 8 12 16 -4 -3.5 -3 -2.5 -2 -1.5 -1 -0.5 0 0.5 1 1.5 2 2.5 3 3.5 4 -16 -12 -8 -4 0 4 8 12 16 -4 -3.5 -3 -2.5 -2 -1.5 -1 -0.5 0 0.5 1 1.5 2 2.5 3 3.5 4 -16 -12 -8 -4 0 4 8 12 16 -4 -3.5 -3 -2.5 -2 -1.5 -1 -0.5 0 0.5 1 1.5 2 2.5 3 3.5 4 -2 -1 0 1 2 -4 -3.5 -3 -2.5 -2 -1.5 -1 -0.5 0 0.5 1 1.5 2 2.5 3 3.5 4 -2 -1 0 1 2
