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.
If you know two sides and an angle which is not inbetween them then you can use the Cosine Rule to find the other side, but it is easier to use the Sine Rule in this situation â you should always use the Sine Rule if you have an angle and its opposite side. to see if you are correct. a2. b2 + c2 â 2bc cos(A)
