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 secant function is the reciprocal of the cosine function the abbreviation of secant is sec the cosecant function is the reciprocal of the sine function the abbreviation of cosecant is csc or cosecthe cotangent function is the reciprocal of the tangent function the abbreviation of cotangent is cotexample given that and that Î¸ is acute find without using a calculator the value of a sec Î¸ b cot Î¸ solution theta is in the first quadrant we can use pythagoras theorem to get the third sidepposite sides adjacent sides and hypotenuse of a right triangle definition of cos sin tan csc sec cot you can use the mathway widget below to practice trigonometry or other math topics try the given examples or type in your own problem
