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.
Cosine: Definition. Given any angle q (0 Â£ q Â£ 90Â°), we can find the cosine of that angle by constructing a right triangle with one vertex of angle q. The cosine is equal to the length of the side adjacent to q, divided by the length of the triangle's hypotenuse.
