Disease-modifying antirheumatic drugs (DMARDs) decrease or stop joint damage caused by rheumatoid arthritis (RA) and other conditions and diseases and can often preserve use of joints.
The Law of Sines (or Sine Rule) is very useful for solving triangles: a sin A = b sin B = c sin C. It works for any triangle: a, b and c are sides. A, B and C are angles. (Side a faces angle A, side b faces angle B and side c faces angle C). And it says that: When we divide side a by the sine of angle A. it is equal to side b divided by the sine of angle B, and also equal to side c divided by the sine of angle C.
sine, sin - ratio of the length of the side opposite the given angle to the length of the hypotenuse of a right-angled triangle. arc sine, arcsin, arcsine, inverse sine - the inverse function of the sine; the angle that has a sine equal to a given number.
