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.
SOH = the sine of an angle is equal to the side opposite the angle divided by the hypotenuse. CAH = the cosine of an angle is equal to the side adjacent to the angle divided by the hypotenuse. TOA-the tangent of an angle is equal to the side opposite the angle divided by the side adjacent to the angle.
