Introduction Prior to 1997, Pennys often shared sites with Vitality Supermarkets, also at that time an ABF subsidiary; however this practice ceased after the sales of PSL to Tesco in 1997. ABF made a decision to maintain control of Primark somewhat than sell it on also, despite the fact that it is the only non-food area of the operation. In July 2005 Primark/Associated British Foods purchased the 120 branch Littlewoods retail string for £409 million. Some of the stores, variously reported as 30 or 50, will be changed into branches of Primark, however the majorities are anticipated to be sold on to other sellers. The Littlewoods catalogue business has been maintained by the Barclay brothers and can continue to operate under the Littlewoods brand.

Secx or secant of x can be written in various forms such as, sec, cosec, and or cot can be defined as a trigonometric function like, sin, cos and tan. Forms of secx include the following: sec x = 1cos x cosec x 1sin x cot x = 1tan x = cos x sin x Secant can as well be obtained from complex number: secx = 2/[e^(ix) + e^(-ix)], where i is the imaginary unit that equals to sqrt (-1). In contrast to cos(x), finding the antiderivative of secant of x needs few calculus tricks. Moreover, the antiderivative of secx has many identical forms that can puzzle students who want to see how good they are at computing.
