What is cot 71°?

Answer

cot 71° ≈
0.3443

Angle in radians: 71° = 71π/180. The point of the angle is in quadrant I, where cotangent is positive.

≈ — rounded to 4 decimal places. cot 71° can't be written with square roots: 71° is not a multiple of 3°.

cot 71° = cos 71° / sin 71° ≈ 0.3443

xyOP

P(cos 71°, sin 71°) ≈ (0.3256, 0.9455)

C(cot 71°, 1) ≈ (0.3443, 1) — where line OP meets the line y = 1.

FAQ

What is cot 71°?

cot 71° ≈ 0.3443

Why does cot 71° 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°. 71° is not, so no such exact form exists; the value is used as a decimal: cot 71° ≈ 0.3443.

Why does a calculator show −0.3249 for cot 71?

The calculator is in radian mode (RAD): it takes cot 71 as the cotangent of 71 radians, cot 71 rad ≈ −0.3249. Switch it to degrees (DEG): cot 71° ≈ 0.3443. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
