It is called a "common logarithm". Engineers love to use it. On a calculator it is the "log" button. It is how many times we need to use 10 in a multiplication, to get our desired number. Example: log (1000) = log10(1000) = 3. 2. Subfactorial: if n is a positive integer, !n is the number of derangements of a set of n elements, and is read as "the subfactorial of n". * Many different uses in mathematics; see Asterisk § Mathematics. | 1.

Unit 2 Solving basic equations & inequalities (one variable, linear) Unit 3 Linear equations, functions, & graphs. Unit 4 Sequences. Unit 5 System of equations. Unit 6 Two-variable inequalities. 1. A crude but easy answer is that to compute n!, you are multiplying n factors which are, on average, of order n. More precisely, let's estimate log(n!) instead of n!. We have logn! = log1 + log2 + log3 + ⋯ + logn. This expression looks like a Riemann sum for ∫ logxdx.The sum of the first \(n\) even integers is \(2\) times the sum of the first \(n\) integers, so putting this all together gives \[\frac{2n(2n+1)}2 - 2\left( \frac{n(n+1)}2 \right) = n(2n+1)-n(n+1) = n^2.\] Even more succinctly, the sum can be written as \[\sum_{k=1}^n (2k-1) = 2\sum_{k=1}^n k - \sum_{k=1}^n 1 = 2\frac{n(n+1)}2 - n = n^2 ...Math explained in easy language, plus puzzles, games, quizzes, worksheets and a forum.

An isosceles triangle has perimeter 30 cm and each of the equal sides is 12 cm. Find the area of the triangle. Solution: Let the sides of an isosceles triangle be. a = 12cm, b = 12cm,c = x cm. Since, perimeter of the triangle = 30 cm. ∴ 12cm + 12cm + x cm = 30 cm. ⇒ x = (30 – 24) = 6.These are symbols that is most commonly used in linear algebra. If x=y, x and y represent the same value or thing. If x≈y, x and y are almost equal. If x≠y, x and y do not represent the same value or thing. If x<y, x is less than y. If x>y, x is greater than y. If x≪y, x is much less than y. z∗ = complex conjugate of z. z ∗ = complex conjugate of z. The Hat symbol can be used to denote a vector.
