Study of triangles and trigonometric functions including sine, cosine, and tangent.
Trigonometric functions can be graphed to show how they change as angles increase.
Graphs help visualize how trig functions behave, making it easier to predict and understand their properties.
The graph of y = sin(x) starts at 0 and goes up to 1, down to -1, and repeats.
y = cos(x) starts at 1 when x = 0 and follows a wave pattern.
Graphs of trig functions show their patterns and help you see how angles affect their values.
