A new way of understanding the activity is born. In the late 60s, the headquarters of the company includes a training school and a laboratory that experiments with products and materials. The company has branches in the major cities of Spain, serving prestigious clients who are slowly beginning to outsource cleaning. The first expansion occurs with the foundation of Prosesa, the current EULEN Security — initiating activities of private security using as an advantage the legal regulation that compels banks and savings banks. DEMASA is founded as a company, dedicated to the manufacture, import and distribution of machinery and chemicals used for cleaning. Activities such as maintenance of facilities, environment, energy control, restoration of facades and monuments, and works commence. The owl is embraced as a symbol of quality in the logo. Alvarez advances a concept of outsourcing as a set of services that allows a company to focus on their core business and not to worry about maintenance and conservation tasks. The Safusa company is created. It is dedicated to the development of new services: geriatric, warehouse control, concierge and guardhouse farms, management of municipal services, customer care centers…. Grupo EULEN celebrates its 25th anniversary and consists of 72 companies with a turnover exceeding 25, million pesetas.

Euler's formula , named after Leonhard Euler , is a mathematical formula in complex analysis that establishes the fundamental relationship between the trigonometric functions and the complex exponential function. Euler's formula states that, for any real number x , one has. Euler's formula is ubiquitous in mathematics, physics, chemistry, and engineering. The physicist Richard Feynman called the equation "our jewel" and "the most remarkable formula in mathematics". Around Leonhard Euler turned his attention to the exponential function and derived the equation named after him by comparing the series expansions of the exponential and trigonometric expressions. Johann Bernoulli had found that [8]. Bernoulli's correspondence with Euler who also knew the above equation shows that Bernoulli did not fully understand complex logarithms. Euler also suggested that complex logarithms can have infinitely many values. The view of complex numbers as points in the complex plane was described about 50 years later by Caspar Wessel.

He introduced much of modern mathematical terminology and notation , including the notion of a mathematical function. Euler is held to be one of the greatest mathematicians in history and the greatest of the 18th century. Several great mathematicians who produced their work after Euler's death have recognised his importance in the field as shown by quotes attributed to many of them: Pierre-Simon Laplace expressed Euler's influence on mathematics by stating, "Read Euler, read Euler, he is the master of us all.
