- Practise questions set in practical situations.
- You will be expected to use both radians and degrees.
- Always check that your calculator is in the correct mode (degrees or radians).
- Check that your answer is sensible, you have answered the question asked, and it is related to the context given.
- Problems may include circular motion, pendulum motion, tides, and biorhythms.
- Be familiar with the concepts of amplitude, period, and frequency and the relationship between period and frequency.
- Use of appropriate technology is expected.
- Check out I Can Do Sheet Level 3 Calculus from www.nzamt.org.nz for a list of essential skills for each achievement standard.
- Using graphics calculators to solve equations for Achievement with Excellence without showing a chain of reasoning, will preclude the award of excellence.
