-- Measure how far the slope rises in 100-ft of horizontal distance.-- That number is the percent of slope, or the "grade".-- If you want the angle of the slope, divide the number by 100, and look upthe "arctangent" of the answer in a table or on a calculator.
You cannot calculate the angle using tangent: you need to use the inverse function: arctangent. The answer will be an angle, x, in the principal range (-90, 90) degrees. But it could be any (x + 180*k) for any integer k.
Here's a list including words (alphabetically) posted by several WikiUsers: Abscissa, absolute, abstract/abstraction, add/addition/additive, affine, algebra/algebraic, algorithm, analog, analysis/analytic/analytical, angle, approximate/approximation, arc/arcsine/arctangent, area, arithmetic/arithmatic, associative, asymtote/asymtotic, axiom/axiomatic,.... There are, doubtless, many others. And some can even be made up using a simple prefix. Here are some examples: a (adimentional), anti (antideritive/antilog/antipode/...),

An arctangent is any of several single-valued or multivalued functions which are inverses of the tangent function.

Angle equals the ArcTangent of (24 /72 ) or = ArcTangent (1/3) Angle is 18.42 degrees. The other larger angle is 71.58 degrees. Link for ArcTangent Calculator: http://www.analyzemath.com/Calculators_2/arctan_calculator.html
It equals the arctangent of the gradient of the incline.

In a crater, the slope of the side of the crater is simply the arc-tangent of the height difference divided by the horizontal distance.
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 tangent, also called the arc-tangent.

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
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).
