The Tangent Curve

Trigonometry · Axiom Academy

Discover why tangent creates a radically different graph with vertical asymptotes and a period of π instead of 2π Tangent is defined as the ratio: . As you move the angle around the unit circle, watch what happens to the tangent value! Now let's watch the tangent graph being drawn as the angle increases. Notice what happens at the special angles! Sine and cosine repeat every 2π (360°), but tangent repeats every π (180°). Let's discover why! Key Features of the Tangent Curve
