Cosine, sine, and tangent are fundamental trigonometric functions that relate the angles of a right triangle to the ratios of its sides. Specifically, the cosine (cos) of an angle is the ratio of the adjacent side to the hypotenuse, the sine (sin) is the ratio of the opposite side to the hypotenuse, and the tangent (tan) is the ratio of the opposite side to the adjacent side. These functions are widely used in mathematics, physics, engineering, and various fields involving angles and periodic phenomena.
sin stands for sine cos stands for cosine and tan stands for tangent
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.
Not sure what the question means. These are abbreviations for the three primary trigonometric functions of angles: sine, cosine and tangent.
Cosecant(Csc) = 1 / Sin . Hence its recip[rocal is 'Sin'(Sine). Similarly Secant(Sec) = 1/ Cos . Hence its reciprocal is 'Cos'(Cosine) Cotangent(Cot) = 1 /Tan . Hence its reciprocal is 'Tan'(Tangent).
Cos is short for Cosine ( Complementary Sine) Similrly Sin is short for Sine Tan is short for Tangent.
Trig identity... sin/cos = tangent

Cos is short for 'Cosine' / It is the complementary curve to 'Sine'.
Zero. Tangent = sine/cosine. sin(0) = 0 and cos(0) = 1, so 0/1 = 0.

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)]
The tangent function is equal to the sine divided by the cosine. In quadrant III, both sin and cos are negative - and a negative divided by another negative is positive. Thus it follows that the tangent is positive in QIII.
Cosecant(Csc) = 1 / Sin . Hence its recip[rocal is 'Sin'(Sine). Similarly Secant(Sec) = 1/ Cos . Hence its reciprocal is 'Cos'(Cosine) Cotangent(Cot) = 1 /Tan . Hence its reciprocal is 'Tan'(Tangent).
Tangent = sine/cosine provided that cosine is non-zero. When cosine is 0, then tangent is undefined.
