The basic ones are: sine, cosine, tangent, cosecant, secant, cotangent; Less common ones are: arcsine, arccosine, arctangent, arccosecant, arcsecant, arccotangent; hyperbolic sine, hyperbolic cosine, hyperbolic tangent, hyperbolic cosecant, hyperbolic secant, hyperbolic cotangent; hyperbolic arcsine, hyperbolic arccosine, hyperbolic arctangent, hyperbolic arccosecant, hyperbolic arcsecant, hyperbolic arccotangent.
The inverse sine is the cosecant, otherwise known as "hypotenuse over opposite" or arcsine. The cosecant is often confused as being the inverse of the cosine, which, in reality, is the secant, otherwise known as "hypotenuse over adjacent" or arccosine.
The basic primitive functions are constant function, power function, exponential function, logarithmic function, trigonometric functions (sine, cosine, tangent, etc.), and inverse trigonometric functions (arcsine, arccosine, arctangent, etc.).
An inverse operation undoes it's composite operation. For example, Addition and Subtraction are inverses of each other, as are Multiplication and Division, as are Exponentiation and Logarithms, as are Sine and ArcSine, Cosine and ArcCosine, Tangent and ArcTangent, Secant and ArcSecant, Cosecant and ArcCosecant, and Cotangent and ArcCotangent
In Excel, the ACos function returns the arccosine (in radians) of a number.The syntax for the ACos function is:ACos( number )number is a number between -1 and 1. It is the cosine of the angle that you wish to find.Applies To:Excel 2007, Excel 2003, Excel XP, Excel 2000
According to SOWPODS (the combination of Scrabble dictionaries used around the world) there are 1 words with the pattern A-CC-----. That is, nine letter words with 1st letter A and 3rd letter C and 4th letter C. In alphabetical order, they are: arccosine
Not so sure about a triangel! There are, in fact 12 trigonometric functions: sine, cosine, tangent; their reciprocals, cosecant, secant and cotangent; and the inverse functions for all six: arcsine, arccosine, arctangent, arccosecant, arcsecant and accotangent. The arc functions are often written with the power -1; that is, arcsin(y) = sin-1(y).
The function sec(x) is the secant function. It is related to the other functions by the expression 1/cos(x). It is not the inverse cosine or arccosine, it is one over the cosine function. Ex. cos(pi/4)= sqrt(2)/2 therefore secant is sec(pi/4)= 1/sqrt(2)/2 or 2/sqrt(2).
