In mathematics, binomial coefficients are represented as \(\binom{a}{b}\), where \(a\) is the \((a-1)^{\text{th}}\) row, and \(b\) is the \((b-1)^{\text{th}}\) number in that row, counting from the left, acting as an index.
Hockey is a team sport that incorporates balance, endurance, and hand-eye coordination. Choosing the proper hockey equipment is important to protect from injuries or dental damage. Hockey players need to drink plenty of water because the heat and weight of the equipment can cause dehydration.
Field hockey presents numerous opportunities for injuries due to the fast paced, repetitive actions of the sport and the use of a long, hard stick and equally hard ball. A high proportion of these injuries can be prevented by ensuring the correct protective equipment is worn.
