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.
In a right triangle, the cosecant of an angle is the length of the hypotenuse divided by the length of the opposite side. In a formula, it is abbreviated to just 'csc'.Of the six possible trigonometric functions, cosecant, cotangent, and secant, are rarely used.ngles greater than 90Â°. In a right triangle, the two variable angles are always less than 90Â° (See Interior angles of a triangle). But we can in fact find the cosecant of any angle, no matter how large, and also the cosecant of negative angles. For more on this see Functions of large and negative angles.
