All three are ratios which do not have units.
sin stands for sine cos stands for cosine and tan stands for tangent
Tangent = sine/cosine provided that cosine is non-zero. When cosine is 0, then tangent is undefined.
Zero. Tangent = sine/cosine. sin(0) = 0 and cos(0) = 1, so 0/1 = 0.
You can choose either or but tangent which is sin/cos seems to be the most common way.
In geometry a Tangent is a straight line that just touches the circumference of a circle.
Trig identity... sin/cos = 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

Sine = -0.5 Cosine = -0.866 Tangent = 0.577
First make sure your calculator is in 'Degree Mode (D)'. Then using the 'Inverse' of 'Sin' , shown as 'ArcSin' or ' Sin^(-1)' . enter '0.5', followed by '=' . The answer should be '30' ( 30 degrees).
to find the measure of an angle. EX: if sin A = 0.1234, then inv sin (0.1234) will give you the measure of angle A
Not sure what the question means. These are abbreviations for the three primary trigonometric functions of angles: sine, cosine and tangent.
Cos is short for Cosine ( Complementary Sine) Similrly Sin is short for Sine Tan is short for Tangent.
