Since the function cosh x is even, only even exponents for x occur in its Taylor series. The sum of the sinh and cosh series is the infinite series expression of the exponential function. The following series are followed by a description of a subset of their domain of convergence, where the series is convergent and its sum equals the function.
A ray through the unit hyperbola = in the point (,), where is twice the area between the ray, the hyperbola, and the -axis. The earliest and most widely adopted symbols use the prefix arc-(that is: arcsinh, arccosh, arctanh, arcsech, arccsch, arccoth), by analogy with the inverse circular functions (arcsin, etc.).
In science, third grade students are taught basic physics and chemistry. Weather and climate are also sometimes taught. The concept of atoms and molecules are common, the states of matter, and energy, along with basic chemical elements such as oxygen, hydrogen, gold, zinc, and iron. Nutrition is also sometimes taught in third grade along with ...
The process for subtracting fractions is, in essence, the same as that of adding them: find a common denominator, and change each fraction to an equivalent fraction with the chosen common denominator. The resulting fraction will have that denominator, and its numerator will be the result of subtracting the numerators of the original fractions.
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.
Circles about the points (0,0), (0,1), (0,2) and (0,3) of radius 3.5 in the Lobachevsky hyperbolic coordinates. Construct a Cartesian-like coordinate system as follows. Choose a line (the x -axis) in the hyperbolic plane (with a standardized curvature of -1) and label the points on it by their distance from an origin ( x =0) point on the x ...
Since cosh x + sinh x = e x, an analog to de Moivre's formula also applies to the hyperbolic trigonometry. For all integers n, ( + ) = + . If n is a rational number (but not necessarily an integer), then cosh nx + sinh nx will be one of the values of (cosh x + sinh x) n. [4]
cosh (mathematical function), hyperbolic cosine, a mathematical function with notation cosh(x)-COSH, a representation of the thiocarboxylic acid functional group in chemistry; Chlorpromazine, an antipsychotic drug; ChromeOS Shell, an operating system designed by Google
