The Pythagorean identity for sine and cosine is cos(a) squared + sin(a) squared = 1 where a is any angle. Other Pythagorean identities can be derived from this one. Create an account to start this course today Used by over30 million studentsworldwide ...
i.e., whether social identity plays a central aspect in a person’s sense of who they are, the centrality scale of the Multidimensional and Multicomponent Measure of Social Identification was used [50]. For the current study, the German version was used [66]. Thereby, identity centrality was...
For Sarasvathy (2001), all entrepreneurs begin with three categories of means: who they are—their traits, tastes, and skills; what they know—their education, training, and experience; and whom they know—their social and professional networks (Sarasvathy, 2001). Research demonstrates the impo...

(Dated: February 1, 2008) 1 In a paper on the significance of the vector potential squared, Gubarev, Stodolsky and Zakharov 1 quote the following identity which holds for vector fields which vanish sufficiently rapidly at infinity that surface terms make no contribution: d 3 xA(...
The 2Î test is a less know alternative to the chi-squared test, with the advantage not to have a constraint on the minimal number of individuals by class. This test is based on the work by the American mathematician Solomon Kullback (1907–1994) in information theory (Kullback,1959). ...
into predefined response options (e.g., “open/poly-relationship”). Participants reported their age (years), height (meters), and weight (kilogram) with free-text responses. For analysis, the body mass index (BMI) was calculated as weight in kilograms divided by height in meters squared [...
