In mathematics, the logarithm is the inverse function to exponentiation. That means that the logarithm of a number x to the base b is the exponent to which b must be raised to produce x. For example, since 1000 = 103, the logarithm base of 1000 is 3, or log10 (1000) = 3.

A magma is a set M matched with an operation • that sends any two elements a, b ∈ M to another element, a • b ∈ M. The symbol • is a general placeholder for a properly defined operation. To qualify as a magma, the set and operation (M, •) must satisfy the following requirement (known as the magma or closure axiom ):
In 2019, McGraw Hill acquired Core-Plus Mathematics Project. In 2020, McGraw Hill became a distributor for Illustrative Mathematics. McGraw Hill was sold in 2021 to Platinum Equity for $4.5 billion. Acquisitions. The McGraw Hill Companies expanded significantly through acquisition, including financial services and broadcasting.
Definitions. Formally, a function is real analytic on an open set in the real line if for any one can write. in which the coefficients are real numbers and the series is convergent to for in a neighborhood of . Alternatively, a real analytic function is an infinitely differentiable function such that the Taylor series at any point in its domain.
Cosine power-reduction formula: an illustrative diagram. The red, orange and blue triangles are all similar, and the red and orange triangles are congruent. The hypotenuse A D ¯ {\displaystyle {\overline {AD}}} of the blue triangle has length 2 cos θ {\displaystyle 2\cos \theta } .
