If an airplane's altitude at time t is a(t), and the air pressure at altitude x is p(x), then (p ∘ a)(t) is the pressure around the plane at time t. Function defined on finite sets which change the order of their elements such as permutations can be composed on the same set, this being composition of permutations.
A formula for computing the trigonometric identities for the one-third angle exists, but it requires finding the zeroes of the cubic equation 4x 3 − 3x + d = 0, where is the value of the cosine function at the one-third angle and d is the known value of the cosine function at the full angle.
A Canadian grandmother of 12 recently broke her second world record of the year — and this time, her incredible feat involved doing over 1,500 push-ups.
A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula.
The 52-year old entrepreneur who was born in South Africa also founded and worked as CEO of Yammer, an enterprise social networking service, which Microsoft acquired for $1.2 billion in 2012. He ...
The study notes that you can consume 5.5 tablespoons of unprocessed cocoa, 2 cups of green tea, or 300 grams of berries to obtain a similar amount of beneficial flavanols as used in the study.
In mathematics, an expansion of a product of sums expresses it as a sum of products by using the fact that multiplication distributes over addition. Expansion of a polynomial expression can be obtained by repeatedly replacing subexpressions that multiply two other subexpressions, at least one of which is an addition, by the equivalent sum of products, continuing until the expression becomes a ...
