Tangent is a function that can have any real value. Therefore one tangent can take any value in (-∞, ∞).
Because the tangent is a function of with the angle as its argument.
The tangent ratio can take any real value.

tangent(54) is about 0.673800101
Angle a, by itself has no value. You must first assign a value to a to get the value of tan a.
The inverse tangent, also called the arc-tangent.
tan(10 deg) = 0.1063, approx.
tan(6 deg) = 0.1051 approx.
tan6=cot(90-6) = cot 84
It is a function which maps the tangent ratio - any real value - to an angle in the range (-pi/2, pi/2) radians. Or (-90, 90) degrees.If tan(x) = y then x is the inverse tangent of y.It is also known as "arc tangent", and spreadsheets, such as Excel, use "atan" for this function.Warning:1/tangent = cotangent is the reciprocal, NOT the inverse.
The graph of the tangent function is periodic at every point. Periodic means that the value of the function at every point is repeated after an integer multiple of the period.
