Maths – NCEA 2.9 Trigonometry – videos and notes to pass the exam
Our simulations are created by analysing exams from the past three years. Our research indicates that our sims include the type of questions that are likely to be asked in the final exams, and that those who use them can increase their learning speed and scores by over 100%. This is a sample only and our sims will offer more questions, videos and tests. Click on the hyperlinks in the table below to watch the short videos that clearly explain how to answer the questions. We are confident these sims will help you to learn how to solve the questions and help you pass your final exams. Send these links to your friends and help them too.

| Achieved Questions | Click on the hyperlinks to watch the video |
|---|---|
| Question 1 | Solve sin x = 0.3, 0°≤ x ≤ 360°degrees) (give answers in degrees) |
| Question 2 | Solve cos x + 0.2 = 0.4, 0°≤ x ≤ 360° (give answers in degrees) |
| Question 3 | Solve 3 tan x = 0.9, 0°≤ x ≤ 360° (give answers in degrees) |
| Question 4 | Solve tan² x = 0.09, 0 ≤ x ≤ 2π (give answers in radians) |
| Question 5 | Solve 4 sin² x = 0.36, 0 ≤ x ≤ 2π (give answers in radians) |
| Question 6 | Solve cos² x - 0.3 = -0.26, 0 ≤ x ≤ 2π (give answers in radians) |
