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.
For the angle Î±, the sine function gives the ratio of the length of the opposite side to the length of the hypotenuse. To define the sine function of an acute angle Î±, start with a right triangle that contains an angle of measure Î±; in the accompanying figure, angle A in triangle ABC is the angle of interest.
