Graph of Trigonometric Function: Sine and Cosine Graph

 * GCSE, IGCSE, AP, PSAT, and IB - Exam Style Questions which covers all the related concepts required for students to unravel any International Exam Style trigonometric graphs Questions
 * Learner will be able to say authoritatively that:
 I can complete any question on how to determine the parameter for a given graph of a trigonometric function
 Sketch or complete the graph for any given sine function
 Sketch or complete the graph for any given cosine function
 Sketch or complete the graph for any given tangent function
 Understand the real-life applications of graph of a trigonometric function
Why do we need to know what trigonometric graphs look like?
• Trigonometric Graphs are used in various applications of mathematics – for example, the oscillating nature can be used to model how a pendulum swings
Drawing graphs – trig graphs
• As with other graphs, being familiar with the general style of trigonometric graphs will help you sketch them quickly and you can then use them to find values or angles alongside your calculator
• All trigonometric graphs follow a pattern – a “starting point” and then “something happens every 90°”.
