Trigonometric Functions: IB A&I SL Question May 2024 P1 Q7 TZ1

In this video, I go over a Trigonometric Functions problem using an IB Applications & Interpretation SL question from May 2024 Paper 1 TZ 1 Question 7. Feel free to open up a blank version of the question here and work along with me: Diagram: https://drive.google.com/file/d/1JFAB... Question: https://drive.google.com/file/d/1gS9A...

Stay tuned as I continue to work through the solutions for this and other IB exams. Excerpt from the question: The following graph shows the depth of water, d metres, in a river at t hours after 12:00. At 15:00, the depth of water reaches 7 m, its highest level. At 21:00, the depth of water drops to 1m, its lowest level. The depth can be modelled by the function d(t)=asin(bt)+4.
