What is cot 61°?

Answer

cot 61° ≈
0.5543

Angle in radians: 61° = 61π/180. The point of the angle is in quadrant I, where cotangent is positive.

≈ — rounded to 4 decimal places. cot 61° can't be written with square roots: 61° is not a multiple of 3°.

cot 61° = cos 61° / sin 61° ≈ 0.5543

xyOP

P(cos 61°, sin 61°) ≈ (0.4848, 0.8746)

C(cot 61°, 1) ≈ (0.5543, 1) — where line OP meets the line y = 1.

FAQ

What is cot 61°?

cot 61° ≈ 0.5543

Why does cot 61° 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°. 61° is not, so no such exact form exists; the value is used as a decimal: cot 61° ≈ 0.5543.

Why does a calculator show 0.2672 for cot 61?

The calculator is in radian mode (RAD): it takes cot 61 as the cotangent of 61 radians, cot 61 rad ≈ 0.2672. Switch it to degrees (DEG): cot 61° ≈ 0.5543. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
