HOMEWORK: MAKING THE DIRECTIONS FOR THE HW MORE CLEAR!!!!!!
- The ideas of amplitude and vertical shift are the same for sin and cos so just stick to one for the whole HW!
- Graph sin(x) or cos(x) parent function (in Y1)
- THEN graph your new function (multiplied by a constant or a constant added to it) (in Y2)
- Choose an "a" value based on the criteria in the question! (a greater than one, a less than -1, or an a value in between -1 and 1)
- Compare these graphs to reveal the effect of a on the graph of sin or cos
- Repeat these steps for page 2
- choose a "v" value based on the criteria (v = 0, v > 0, v < 0)
- Compare the graphs to reveal the effect of vertical shift on a graph of sin or cos
- Repeat these steps for page 3
- keep v constant throughout the page to show the effects of amplitude and vertical shift without it being too confusing
- compare the graphs to reveal how vertical shift and amplitude work together to change the graph
- Use your definitions of amplitude (1d) and vertical shift (2d) to answer the last question (3d)
- Use your graphing calculator (online calculator on the blog in links)
- If you're having trouble with this check in the book for examples
- Amplitude (pg 289)
- Vertical Shift (pg 292)
Here's a key to the classwork (including the other side that we didn't get to)
