👉 Sinical is a term in mathematics that refers to a special case of the hyperbolic sine function, defined for angles between 0 and π/2 radians. This value is often used when discussing the behavior of trigonometric functions at certain angles. In the context of the hyperbolic sine function, sinical is a specific type of the hyperbolic cosine, which is a special case where the argument (x) is an angle that lies between 0 and π/2 radians
