Graph of y = sin x

Properties of the Sine Curve

1. The period is 360^o.

2. The amplitude is 1, meaning the range is between -1 and 1 inclusive.

3. The graph is symmetrical about the origin.

4. The curve is continuous.

Graph of y = cos x

Properties of the Cosine Curve

1. The period is 360^o.

2. The range is between -1 and 1 inclusive.

3. The graph is symmetrical about the y-axis.

4. The curve is continuous.

Graph of y = tan x

Properties of Tangent Curve

1. The period is 180^o.

2. The range is all real numbers.

3. The graph is symmetrical about the origin.

4. The curve is not continuous. There are vertical asymptotes at x = 90^o, 270^o,...
