Is tangent equal to sine over cosine?

So far in this course, the only trigonometric functions which we have studied are sine and cosine. The tangent of x is defined to be its sine divided by its cosine: tan x = sin x cos x . The cotangent of x is defined to be the cosine of x divided by the sine of x: cot x = cos x sin x .

Hereof, what is tan in trigonometry?

Tangent (tan) function - Trigonometry. (See also Tangent to a circle). In a right triangle, the tangent of an angle is the length of the opposite side divided by the length of the adjacent side.

What is tan function?

Sine, Cosine and Tangent are the main functions used in Trigonometry and are based on a Right-Angled Triangle. Before getting stuck into the functions, it helps to give a name to each side of a right triangle: "Opposite" is opposite to the angle θ "Adjacent" is adjacent (next to) to the angle θ
