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.
Definition 1 is the simplest and most intuitive definition of the sine and cosine function. The sine definition basically says that, on a right triangle, the following measurements are related: the measurement of one of the non-right angles (q) the length of the side opposite to that angle.
