Outline:

Trig Tour A unit circle to find the trigonometric ratios. Construct right angled triangles inside a unit circle. Convert degrees into radians to look at the periodicity of functions. Special angle values for theta (θ). Coordinates of points tracing the trigonometric functions. Cosine function graph. Sine function graph. Tangent function graph. Amplitude of the functions. Vertical asymptotes of the tangent function.
