What is cot 82°?

Answer

cot 82° ≈
0.1405

Angle in radians: 82° = 41π/90. The point of the angle is in quadrant I, where cotangent is positive.

≈ — rounded to 4 decimal places. cot 82° can't be written with square roots: 82° is not a multiple of 3°.

cot 82° = cos 82° / sin 82° ≈ 0.1405

xyOP

P(cos 82°, sin 82°) ≈ (0.1392, 0.9903)

C(cot 82°, 1) ≈ (0.1405, 1) — where line OP meets the line y = 1.

FAQ

What is cot 82°?

cot 82° ≈ 0.1405

Why does cot 82° have no exact value?

A trigonometric value of a whole number of degrees can be written with square roots only when the angle is a multiple of 3°. 82° is not, so no such exact form exists; the value is used as a decimal: cot 82° ≈ 0.1405.

Why does a calculator show 3.0319 for cot 82?

The calculator is in radian mode (RAD): it takes cot 82 as the cotangent of 82 radians, cot 82 rad ≈ 3.0319. Switch it to degrees (DEG): cot 82° ≈ 0.1405. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
