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.
Sine and Cosine: Overview. The sine (abbreviated sin) and cosine (cos) are the two most prominent trigonometric functions. All other trig functions can be expressed in terms of them. In fact, the sine and cosine functions are closely related and can be expressed in terms of each other.
