-- 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.
arctangent
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 angle of friction is the angle at which a body will start sliding on a surface. It is equal to the arctangent of the coefficient of static friction between the two surfaces in contact.
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 angle that the velocity makes with the horizontal is called the launch angle. It can be calculated using trigonometry by finding the arctangent of the vertical component of the velocity divided by the horizontal component.
The inverse tangent, also called the arc-tangent.

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.).
