In mathematics, the trigonometric functions (also called the circular functions) are functions of an angle. They relate the angles of a triangle to the lengths of its sides. Trigonometric functions are important in the study of triangles and modeling periodic phenomena, among many other applications.
Yellow stool is generally a sign that food has passed through the digestive tract too quickly. Because bile salts from the liver give stool its brown color, yellow stool can indicate abnormalities with the gallbladder and liver. Healthgrades states that it can also be caused by an infection such as giardiasis.
