English: Animated plot of the trigonometric (circular) and hyperbolic functions.
In red, curve of equation x² + y² = 1 (unit circle), and in blue, x² - y² = 1 (equilateral hyperbola), with the points (cos(θ),sin(θ)) and (1,tan(θ)) in red and (cosh(θ),sinh(θ)) and (1,tanh(θ)) in blue.
Français : Diagramme animé des fonctions trigonométriques usuelles et des fonctions hyperboliques
En rouge, la courbe d'équation x² + y² = 1 (le cercle unité), et en bleu celle d'équation, x² - y² = 1 (l'hyperbole équilaterale), avec les points points (cos(θ),sin(θ)) et (1,tan(θ)) représentés en rouge, ainsi que (cosh(θ),sinh(θ)) et (1,tanh(θ)) représenté en bleu.

for red points,(1,tan∅)have the unlimited Y value; while (1,tanh∅)'s maximal y vlue is 1.That's what you see in this animated graph.
