Contango is a situation in which the futures price (or forward price) of a commodity is higher than the expected spot price of the contract at maturity. [1] In a contango situation, arbitrageurs or speculators are "willing to pay more [now] for a commodity [to be received] at some point in the future than the actual expected price of the ...
The concept started to be used by oil traders in the market in early 1990. [2] But it was in 2007 through 2009 that the oil storage trade expanded. [6] Many participants—including Wall Street giants, such as Morgan Stanley, Goldman Sachs, and Citicorp—turned sizeable profits simply by sitting on tanks of oil. [5]
A computer algebra system (CAS) is a software product designed for manipulation of mathematical formulae.The principal objective of a computer algebra system is to systematize monotonous and sometimes problematic algebraic manipulation tasks.
A 104-key PC US English QWERTY keyboard layout with the numeric keypad at the far right. Numeric keypads are also used for playing some oldercomputer games where the player must control a character, such as roguelikes and Sid Meier's Pirates!. Unlike arrow keys, the numeric keypad can allow for diagonal movement.
More formulas of this nature can be given, as explained by Ramanujan's theory of elliptic functions to alternative bases. Perhaps the most notable hypergeometric inversions are the following two examples, involving the Ramanujan tau function τ {\displaystyle \tau } and the Fourier coefficients j {\displaystyle \mathrm {j} } of the J-invariant ...
In computing, a keyboard shortcut is a sequence or combination of keystrokes on a computer keyboard which invokes commands in software.. Most keyboard shortcuts require the user to press a single key or a sequence of keys one after the other.
A simple arithmetic calculator was first included with Windows 1.0. [5]In Windows 3.0, a scientific mode was added, which included exponents and roots, logarithms, factorial-based functions, trigonometry (supports radian, degree and gradians angles), base conversions (2, 8, 10, 16), logic operations, statistical functions such as single variable statistics and linear regression.
Michael Danos and Johann Rafelski edited the Pocketbook of Mathematical Functions, published by Verlag Harri Deutsch in 1984. [14] [15] The book is an abridged version of Abramowitz's and Stegun's Handbook, retaining most of the formulas (except for the first and the two last original chapters, which were dropped), but reducing the numerical tables to a minimum, [14] which, by this time, could ...
