What is cot 211°?

Answer

cot 211° ≈
1.6643

Angle in radians: 211° = 211π/180. The point of the angle is in quadrant III, where cotangent is positive.

≈ — rounded to 4 decimal places. cot 211° can't be written with square roots: 211° is not a multiple of 3°.

cot 211° = cot(180° + 31°) = cot 31° ≈ 1.6643

cot 211° = cos 211° / sin 211° ≈ 1.6643

xyOP

P(cos 211°, sin 211°) ≈ (−0.8572, −0.5150)

C(cot 211°, 1) ≈ (1.6643, 1) — where line OP meets the line y = 1, on the extension of the ray beyond O (dashed).

FAQ

What is cot 211°?

cot 211° ≈ 1.6643

Why does cot 211° 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°. 211° is not, so no such exact form exists; the value is used as a decimal: cot 211° ≈ 1.6643.

Why does a calculator show 1.7740 for cot 211?

The calculator is in radian mode (RAD): it takes cot 211 as the cotangent of 211 radians, cot 211 rad ≈ 1.7740. Switch it to degrees (DEG): cot 211° ≈ 1.6643. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
