Which equation matches this wave? Task 1
Identify What is the amplitude of this wave? Task 2
Identify How many complete cycles appear between x = 0 and x = 2π ≈ 6.28? Task 3
Identify Start with Identify the Equation to match the wave to its formula. Each task asks you to read the graph and pick the right answer.
Tip: Check the height of the peaks for the amplitude, and count how many full cycles appear in a known interval for the frequency.
