Written by Calculates the hyperbolic sine for any real number.
Computes the sine of an angle expressed in radians.
Given a numeric input, returns `-1` for negative numbers, `1` for positive numbers, and `0` for zero.
For parameters x, n, m, and a, this function computes the sum of a power series: a1 * x^n + a2 * x^(n+m) + … + ai * x^(n+(i-1)m), where i denotes the count of values within the range ‘a’.
Produces a series of consecutive numbers, like 1, 2, 3, 4…
The SECH function calculates the hyperbolic secant of a specified angle.
The SEC function calculates the secant of an angle, expressed in radians.
Rounds a number up to the specified number of decimal places, ensuring that it always moves to the next higher increment.
Adjusts a number to a specified number of decimal places, consistently rounding down to the nearest valid increment.
Adjusts a number to a specified number of decimal places following conventional rounding methods.
