If you square a negative does the negative sign stay? Prove that cos(sin^{-1} x) = square root (1 - x^2). Prove that cos(sin^{-1} x) = square root of {1 - x^2} . Suppose that the number, ''z,'' is imaginary. Is the number, ''zi,'' real? (if i=radical -1) ...
It’s a long story, told elsewhere right here at my long-established, no-clickbait site (where the lead article is a longer version of the points I want to make now), but here I am: a guy who is really serious about History, I do have a nice degree in the subject, and I’ve ...
The last two decades saw radical changes in genetics and genomics. It took more than 15 years to crack the code of the human DNA: theHuman Genome Projectstarted in 1990, cost billions of dollars and could present its final results in 2006. In contrast, by now, there aremore than 2,000...
a contested concept, mainly concerning the magnitude of the (intended) social change. One school of thought sees social innovation as any innovation outcome which better addresses societal needs (seePol and Ville, 2009). A second, more radical, tradition sees social innovation as a process ...
Optimism bias refers to the tendency to overestimate the likelihood of positive outcomes and underestimate the likelihood of negative outcomes. In oncology care, optimism bias contributes to overestimating patient prognosis110 or the likelihood of benefit from a particular treatment and underestimating the ...
Diversifying agriculture by rotating a greater number of crop species in sequence is a promising practice to reduce negative impacts of crop production on the environment and maintain yields. However, it is unclear to what extent cereal yields change with crop rotation diversity and external nitrogen...
In the physical range of parameters, this polynomial admits either one real radical having the order of multiplicity four or three distinct radicals also having the order of multiplicity four. It turned out that the same set of radicals are obtained when making substitution with ψ2 of ψ3. ...
Yet what it recalls is one of the more negative elements of the wilderness years: “You shall live in booths seven days; all citizens in Israel shall live in booths, so that future generations may know that I made the Israelites live in booths when I brought them out of the land of Eg...
The negative arousal is associated with safety-seeking and other avoidant behaviours Such experiences are more complex than the stress one would experience during a driving test which might have even resulted in failure and subsequent self-criticism. As upsetting as that can be, it does not amount...
A variation of the fine structure constantα=e2ℏcis more radical in comparison; as it is directly related to the variation of eithere, permittivity of free space or the speed of lightc. There are some models on varying speed of light providing possible resolutions to some cosmological issues...
