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.

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

Divide "1" by the argument "z" of the arcsec(z) function. Note, that "z" is equal to secant(angle) and 1/z is cosine (angle).For example, if arcsec(4) then cosine is "1/4" value or 0.25.Using a calculator, calculate the arccosine (arccos) function of "1/z" to get arcsec(z). Angle=arcsec(z)= arccos(1/z).In the example, arcsec(4)= arccos(0.25)=75.52 degrees.Calculate arcsecant if the function is given as arcsec(sec(Z)) e.g. arcsec(sec(45)). In such a case you do not need to calculate the secant value and then follow Steps 1 and 2. Instead, get an instant answer: arcsec equals Z. In this example, arcsecant of sec(45) is 45.

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).

Trigonometry includes 12 baisic functions. Sine, Cosine, and Tangent are the three most baisic. Each of those functions has a reciprocal. Cosine's reciprocal is Secant, Sine reciprocal is Cosecant, and Tangent's reciprocal is Cotangent. Each of those six functions has an inverse funcion called Inverse Sine, Cos etc... or Arcsine, Arcosine, Arcsecant, etc.... The shorthand for each function is sin, caos, tan, sec, csc, cot. The inverses have a -1 notation like sin-1.
