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].

What does tan equal in trigonometry?
Opposite side over Adjacent side, or sine/cosine
How is tan equal to undefined?
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.
What do sin and cos mean in math?
sin stands for sine cos stands for cosine and tan stands for tangent
How do you express complementary angles into a trigonometric function?
The sine of an angle is the cosine of its complement and conversely. The tan of an angle is the reciprocal of its complement.
Why are cosines positive and negative?
Because the cosine of some angles is positive and the cosine of some other angles is negative.
What is the relationship between the tan and cot?
Cotangent is 1 / tangent. Since tangent is sine / cosine, cotangent is cosine / sine.
What does tan equal in trigonometry?
Opposite side over Adjacent side, or sine/cosine
What is Sin cosine and tangent?
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

What are the sum and difference identities for the sine cosine and tangent functions?
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)]
How do you write ratios for sin and cosine?
sin = opp/hyp cos = adj/hyp tan = opp/adj
What do sin and cos mean in math?
sin stands for sine cos stands for cosine and tan stands for tangent
How do you express complementary angles into a trigonometric function?
The sine of an angle is the cosine of its complement and conversely. The tan of an angle is the reciprocal of its complement.
Why are cosines positive and negative?
Because the cosine of some angles is positive and the cosine of some other angles is negative.
How to find the height of the sun?
It can be found out through applying Sine/Cosine/tan to the angles of for example a shadow of a building due to sun.
What does sin cos and tan?
Not sure what the question means. These are abbreviations for the three primary trigonometric functions of angles: sine, cosine and tangent.
What is cosine cubed?
It is cosine*cosine*cosine.
