Proponents of the alkaline diet suggest that a diet high in acid-producing foods disrupts the blood's normal pH level and, in turn, triggers the loss of essential minerals (such as calcium) as the body attempts to restore equilibrium. This imbalance is said to increase susceptibility to illness.
The law of cosines is useful for computing the third side of a triangle when two sides and their enclosed angle are known, and in computing the angles of a triangle if all three sides are known.
The sine of one of the angles of a right triangle (often abbreviated sin) is the ratio of the length of the side of the triangle opposite the angle to the length of the triangle's hypotenuse. The cosine (often abbreviated cos) is the ratio of the length of the side adjacent to the angle to the length of the hypotenuse. And the tangent (often abbreviated tan) is the ratio of the length of the side opposite the angle to the length of the side adjacent.
