For the above isosceles triangle with unit sides and angle , the area 1 / 2 × base × height is calculated in two orientations. When upright, the area is sin θ cos θ {\displaystyle \sin \theta \cos \theta } .
However, this might appear to conflict logically with the common semantics for expressions such as sin 2 (x) (although only sin 2 x, without parentheses, is the really common use), which refer to numeric power rather than function composition, and therefore may result in confusion between notation for the reciprocal (multiplicative inverse) and ...
Symbolab is an answer engine [1] that provides step-by-step solutions to mathematical problems in a range of subjects. [2] It was originally developed by Israeli start-up company EqsQuest Ltd., under whom it was released for public use in 2011.

The names exsecant, versine, chord, etc. can also be applied to line segments related to a circular arc. [2] The length of each segment is the radius times the corresponding trigonometric function of the angle. The external secant function (abbreviated exsecant, symbolized exsec) is a trigonometric function defined in terms of the secant function:

Reed's thesis research concerned perfect graphs. [5] With Michael Molloy, he is the author of a book on graph coloring and the probabilistic method. [9] Reed has also published highly cited papers on the giant component in random graphs with a given degree sequence, random satisfiability problems, acyclic coloring, tree decomposition, and constructive versions of the Lovász local lemma.
