Trigonometry (from Greek trigōnon "triangle" + metron"measure"[1]) is a branch of mathematics that studies triangles and the relationships between their sides and the angles between these sides. Trigonometry defines the trigonometric functions‚ which describe those relationships and have applicability to cyclical phenomena‚ such as waves. The field evolved during the third century BC as a branch of geometry used extensively for astronomical studies.[2] It is also the foundation of the practical art

CHAPTER ONE INTRODUCTION/LITERATURE REVIEW THE ERYTHROCYTES A cell that contains haemoglobin and can carry oxygen to the body. Also called a red blood cell (RBC). The reddish colour is due to haemoglobin. Erythrocytes are biconcave in shape which increases the cells surface area and facilitates the diffusion of oxygen and carbon dioxide. This shape is maintained by a cytoskeleton composed of several proteins. Erythrocytes
