- Identify if there is a negative and which way it will start
- Find the period by using the formula 2pie/b
- Find the amplitude (the x's coefficient)
- Write the 5 points (o, pie/2, pie, 3pie/2, 2pie)
- Divide every term by the "B" term in your given equation
- If anything is added/subtracted then, do the opposite to get 5 new points
- Sketch
- Shift points up or down if, anything is added or subtracted outside of the parenthesis
Example: -2Sin (pie/2x-1)
1) Sketch to get a visual
2) Find period using formula. P=4
3) Amplitude=2
4) Add 1 to your 5 points. New points: 1,2,3,4,5
5) Sketch
