The following problem can be used as a warm-up
to the lesson on cofunctions.
Grab your graphing calculator!
1. Set the mode to radians, and
complete the following chart.
You are given:
|
|
|
| x | 0.2 | 0.4 | 0.6 | 0.7 | 0.8 | 1 | 1.2 | 1.4 |
| y1 | ||||||||
| y2 |
Draw a conclusion based upon your findings.
2. Examine your findings further by graphing each of the given equations. Set the "bubble" animation (to the left of y1 on the calculator) for the second equation.
Do the graphs support your conclusion from question 1?
