Programme

Last lesson's

Intended Learning Outcomes

At the end of the lesson you could...

1. Set up your own exponential formula
   
2. Recognize and apply exponential growth vs. decay
   
3. Combine percentages with exponential formulas

Fieke starts with 250 euros in her porcelain piggy bank. Unfortunately, she loses 11.5% each day due to a leak in the bottom.
Set up a formula and calculate how much money she will have left after 5 days.

1. 0.01 euros
2. 36.10 euros
3. 106.25 euros
4. 135.72 euros

Intended Learning Outcomes

At the end of the lessons you could...

1. Use sin/cos/tan and their inverses appropriately in right-angled triangles to calculate sides and angles
2. Use these trigonometric ratios in contexts and situations by sketching and/or drawing auxiliary lines
   
3. Set up your own exponential formula and recognize and apply exponential growth vs. decay
4. Combine percentages with exponential formulas

Options

• Pick one Mixed Exercise (ch.7/8)
• Work together on it
• Present your findings at the end
  ór...
• Do a longer practice test
• No presentations
• ...but also no solutions 

Which do you prefer?

Specific exercise with presentations at the end

Longer practice test without presentations at the end

Which of the goals would you like to practice with?

1. Use sin/cos/tan and their inverses appropriately

2. Apply sin/cos/tan and their inverses in contexts and situations

3. Set up exponential formulas with growth and decay

4. Combine exponential growth with percentages

Exercises

• Do the exercise together with your group mates (20 min)
• One person uploads a picture, one person presents their group's findings
• Done quickly? Continue with ME1-7 (ch.7) and/or ME1-2 (ch.8)

1. Use trigonometry appropriately

Do 1
(Mixed Ex. ch.7)

2. Use trigonometry in situations

Do 6
(Mixed Ex. ch.7)

3. Set up exponential formulas

Do 2
(Mixed Ex. ch.8)

4. Combine percentages with exponential formulas

Do 1
(Mixed Ex. ch.8)

Practice test

• Optional: hand in pictures of (some of) your answers and receive feedback
   Deadline: Saturday, 21:00
  
  
• Good luck with studying!
