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) function-Trigonometry. In a right triangle, the sine of an angle is the length of the opposite side divided by the length of the hypotenuse.Try this Drag any vertex of the triangle and see how the sine of A and C are calculated.n any right triangle, the sine of an angle x is the length of the opposite side (O) divided by the length of the hypotenuse (H). In a formula, it is written as 'sin' without the 'e': Often remembered as SOH - meaning S ine is O pposite over H ypotenuse.
