What's on the worksheet

  1. Each interval is a quarter-turn stretch between two neighboring key points.
    \left(\dfrac{\pi}{2}, \pi\right)\left(-\dfrac{\pi}{2}, 0\right)\left(\dfrac{5\pi}{2}, 3\pi\right)\left(-3\pi, -\dfrac{5\pi}{2}\right)\left(\dfrac{7\pi}{2}, 4\pi\right)
  2. Each list is meant to be the five key points of one cycle of y = x or of y = x.
  3. Use the graph of y = x on [-π, 3π].
    c = 1c = 0.3c = -1c = -0.95c = -1.2
  4. Sketch y = x on [-3π2, π].
  6. The figure shows y = x with the x-axis marked every π2.
