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.
The arctan function is the inverse of the tangent function. It returns the angle whose tangent is a given number. Try this Drag any vertex of the triangle and see how the angle C is calculated using the arctan() function. For every trigonometry function, there is an inverse function that works in reverse. These inverse functions have the same name but with 'arc' in front. (On some calculators the arctan button may be labelled atan, or sometimes tan-1.) So the inverse of tan is arctan etc.
