2. List of trigonometric identities - Wikipedia

   en.wikipedia.org/wiki/List_of_trigonometric...

   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

3. Law of cotangents - Wikipedia

   en.wikipedia.org/wiki/Law_of_cotangents

   In trigonometry, the law of cotangents is a relationship among the lengths of the sides of a triangle and the cotangents of the halves of the three angles. [1] [2]Just as three quantities whose equality is expressed by the law of sines are equal to the diameter of the circumscribed circle of the triangle (or to its reciprocal, depending on how the law is expressed), so also the law of ...

5. Trigonometric functions - Wikipedia

   en.wikipedia.org/wiki/Trigonometric_functions

   Sin(θ), Tan(θ), and 1 are the heights to the line starting from the x-axis, while Cos(θ), 1, and Cot(θ) are lengths along the x-axis starting from the origin. If the acute angle θ is given, then any right triangles that have an angle of θ are similar to each other. This means that the ratio of any two side lengths depends only on θ.

   Spray-on car wax is the easiest to apply and remove. However, spray-on car waxes do not clean deeply, are less weather-resistant, and generally have the poorest durability. That makes them best ...

7. Hyperbolic secant distribution - Wikipedia

   en.wikipedia.org/wiki/Hyperbolic_secant_distribution

   The hyperbolic secant distribution shares many properties with the standard normal distribution: it is symmetric with unit variance and zero mean, median and mode, and its probability density function is proportional to its characteristic function.
