The trigonometry identity is [tex]\tan x=\frac{\sin x}{\cos x}[/tex].
What is trigonometry ratios?
Trigonometric ratios are the ratios of the sides of a right triangle. The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).
What is the formula of tanx?
The tan x is given by (sin x)/ (cos x) as the formula is [tex]\tan x=\frac{\sin x}{\cos x}[/tex].
This is same as option B.
Therefore, the correct answer is [tex]\frac{\sin x}{\cos x}[/tex] which is option B.
