U.S. Attorney Matt M. Dummermuth says the operation was the largest single-site immigration raid in U.S. history. Braley wants tally on immigration raids. Associated Press, May 21, 2008 DES MOINES, Iowa - U.S Rep. Bruce Braley wants to know the cost of Immigration raids at meatpacking plants.
The idea is the same in trigonometry. Inverse trig functions do the opposite of the âregularâ trig functions. Inverse sine (sinâ1)(\sin^{-1})(sinââ1ââ)left parenthesis, sine, start superscript, minus, 1, end superscript, right parenthesis does the opposite of the sine.
Note that in the notation (commonly used in North America and in pocket calculators worldwide), denotes the tangent and the inverse function, not the multiplicative inverse. The principal value of the inverse tangent is implemented as ArcTan[z] in the Wolfram Language. In the GNU C library, it is implemented as atan(double x). The inverse tangent is a multivalued function and hence requires a branch cut in the complex plane, which the Wolfram Language's convention places at and . This follows from the definition of as (1)
