Any number can be a tan. So -sqrt(17), 19.56, 45678942 are all examples of tan.
Cosine can have any value in the range [-1, 1].
Tan of pi/2 + k*pi radians, for integer k, is not defined since tan = sin/cos and the cosine of these angles is 0. Since divsiion by 0 is not defined, the tan ratio is not defined.
sin stands for sine cos stands for cosine and tan stands for tangent
The sine of an angle is the cosine of its complement and conversely. The tan of an angle is the reciprocal of its complement.
Because the cosine of some angles is positive and the cosine of some other angles is negative.
It can be found out through applying Sine/Cosine/tan to the angles of for example a shadow of a building due to sun.
Cotangent is 1 / tangent. Since tangent is sine / cosine, cotangent is cosine / sine.
Sin, cosine, and tangent are considered the three main of trigonometry, commonly written as sin, cos, and tan. sin(θ) = O/H cos(θ) = A/H tan(θ) = O/A Where O is opposite Where H is Hypotenuse Where A is Adjacent To assist further in understanding: http://www.mathsisfun.com/sine-cosine-tangent.html

Sine sum identity: sin (x + y) = (sin x)(cos y) + (cos x)(sin y)Sine difference identity: sin (x - y) = (sin x)(cos y) - (cos x)(sin y)Cosine sum identity: cos (x + y) = (cos x)(cos y) - (sin x)(sin y)Cosine difference identity: cos (x - y) = (cos x)(cos y) + (sin x)(sin y)Tangent sum identity: tan (x + y) = [(tan x) + (tan y)]/[1 - (tan x)(tan y)]Tangent difference identity: tan (x - y) = [(tan x) - (tan y)]/[1 + (tan x)(tan y)]
sin = opp/hyp cos = adj/hyp tan = opp/adj

Not sure what the question means. These are abbreviations for the three primary trigonometric functions of angles: sine, cosine and tangent.
It is cosine*cosine*cosine.
No; those could be three different values, or sometimes two of them might be the same. For example, if the angle is 45 degrees, the values are about... cos:0.707 sin: 0.707 tan: 1 For 45 degrees, the cosine and sine are the same. For 36 degrees, cos:0.809 sin: 0.588 tan: .727
