The Graphs of Sine, Cosine and Tangent

What you need to learn in this topic

1. Draw graphs of trigonometric functions y = sin x, y = cos x dan y = tan x for 0 ≤ x ≤ 360, hence compare and contrast the characteristics of the graphs.
2. Investigate and make generalisations about the effects of changes in constants a, b and c on the graphs of trigonometric functions: (i) y = a sin bx + c (ii) y = a cos bx + c (iii) y = a tan bx + c for a > 0, b > 0.
3. Solve problems involving graphs of sine, cosine and tangent functions.
