View All. Biologic drugs, which have been marketed for certain types of inflammatory arthritis since 1998, are administered either by infusion or self-injection. Side effects, which can occur with these drugs, are referred to as infusion reactions or injection site reactions.
Reciprocal identities[edit] The cosecant ( csc {\displaystyle \csc } ), secant ( sec {\displaystyle \sec } ) and cotangent ( cot {\displaystyle \cot } ) functions are 'convenience' functions, just the reciprocals of (that is 1 divided by) the sine, cosine and tangent. So.
The sine of one of the angles of a right triangle (often abbreviated sin) is the ratio of the length of the side of the triangle opposite the angle to the length of the triangle's hypotenuse. The cosine (often abbreviated cos) is the ratio of the length of the side adjacent to the angle to the length of the hypotenuse. And the tangent (often abbreviated tan) is the ratio of the length of the side opposite the angle to the length of the side adjacent.
