The trigonometric functions are also important in physics. The sine and the cosine functions, for example, are used to describe simple harmonic motion, which models many natural phenomena, such as the movement of a mass attached to a spring and, for small angles, the pendular motion of a mass hanging by a string.
Stools that are pale, white, or look like clay or putty may be the result of a lack of bile or by a blockage in the bile ducts. Stools that are light in color or look like clay can also occur after a test in the colon that uses barium (such as a barium enema), because the barium may be passed in the stool.
