In statistics, the 68–95–99.7 rule, also known as the empirical rule, and sometimes abbreviated 3sr, is a shorthand used to remember the percentage of values that lie within an interval estimate in a normal distribution: approximately 68%, 95%, and 99.7% of the values lie within one, two, and three standard deviations of the mean, respectively.
Unary operation. In mathematics, a unary operation is an operation with only one operand, i.e. a single input. [1] This is in contrast to binary operations, which use two operands. [2] An example is any function f : A → A, where A is a set. The function f is a unary operation on A .
It can be adapted to similar equations e.g. F = ma, v = fλ, E = mcΔT, V = π r 2 h and τ = rF sinθ / - for more examples, see this SVG cheat sheet on Wikimedia Commons. When a variable with an exponent or in a function is covered, the corresponding inverse is applied to the remainder, i.e. r = √ V / π h and θ = arcsin τ ...
