What is cot 127°?

Answer

cot 127° ≈
−0.7536

Angle in radians: 127° = 127π/180. The point of the angle is in quadrant II, where cotangent is negative.

≈ — rounded to 4 decimal places. cot 127° can't be written with square roots: 127° is not a multiple of 3°.

cot 127° = cot(180° − 53°) = −cot 53° ≈ −0.7536

cot 127° = cos 127° / sin 127° ≈ −0.7536

xyOP

P(cos 127°, sin 127°) ≈ (−0.6018, 0.7986)

C(cot 127°, 1) ≈ (−0.7536, 1) — where line OP meets the line y = 1.

FAQ

What is cot 127°?

cot 127° ≈ −0.7536

Why does cot 127° 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°. 127° is not, so no such exact form exists; the value is used as a decimal: cot 127° ≈ −0.7536.

Why does a calculator show 0.2389 for cot 127?

The calculator is in radian mode (RAD): it takes cot 127 as the cotangent of 127 radians, cot 127 rad ≈ 0.2389. Switch it to degrees (DEG): cot 127° ≈ −0.7536. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
