In mathematics, hyperbolic functions are analogues of the ordinary trigonometric functions, but defined using the hyperbola rather than the circle. Just as the points (cos t, sin t) form a circle with a unit radius, the points (cosh t, sinh t) form the right half of the unit hyperbola.

COSH Training or Construction Occupational Safety and Health Training is a 40-hour mandatory training for officers in the construction works. The COSH Training aims to equip participants with the basic knowledge and skills in performing safety audits, assessments and analysis of hazards and risks in the construction industry.

Provides information on the Control of substances hazardous to health (COSHH). Using chemicals or other hazardous substances at work can put peoples health at risk.

2024年11月24日 · cosh算法，即双曲余弦函数算法，是数学和计算机科学中常用的函数之一。 它广泛应用于工程计算、物理建模、图像处理等领域。 本文将深入探讨cosh算法的原理，并介绍其在实际应用中的案例。

The objective of Construction Occupational Safety and Health (COSH) Training for Safety Officer 2 is to provide safety officers working in the construction industry with advanced knowledge and skills in occupational safety and health.

$\text{cosh}\ 2x = \text{cosh}^2x + \text{sinh}^2x= 2 \text{cosh}^2x - 1 = 1 + 2 \text{sinh}^2x$ $\text{tanh}\ 2x = \frac{2\text{tanh}\ x}{1 + \text{tanh}^2x}$ Half angle formulas

Safety data sheets provide information on chemical products that help users of those chemicals to make a risk assessment. They describe the hazards the chemical presents, and give...

COSHH covers chemicals, products containing chemicals, fumes, dusts, vapours, mists and gases, and biological agents (germs). If the packaging has any of the hazard symbols then it is classed as a...
