Trigonometric Ratios And Graphs
Gbogbo ọrọ náà
Trigonometric ratios connect angles to lengths, and their graphs reveal the repeating patterns that underpin everything from sound waves to satellite orbits. Mastering the exact values for the standard angles and knowing how sine, cosine and tangent behave beyond the first quadrant is the gateway to every other trigonometry topic in the 4PM1 specification.
In this lesson you will learn to evaluate sin, cos and tan for any angle, sketch the three core graphs from memory, recall the exact values for 30, 45 and 60 degrees (and their radian equivalents), and use symmetry to find trigonometric ratios of related angles in all four quadrants.
