What is cot 56°?

Answer

cot 56° ≈
0.6745

Angle in radians: 56° = 14π/45. The point of the angle is in quadrant I, where cotangent is positive.

≈ — rounded to 4 decimal places. cot 56° can't be written with square roots: 56° is not a multiple of 3°.

cot 56° = cos 56° / sin 56° ≈ 0.6745

xyOP

P(cos 56°, sin 56°) ≈ (0.5592, 0.8290)

C(cot 56°, 1) ≈ (0.6745, 1) — where line OP meets the line y = 1.

FAQ

What is cot 56°?

cot 56° ≈ 0.6745

Why does cot 56° 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°. 56° is not, so no such exact form exists; the value is used as a decimal: cot 56° ≈ 0.6745.

Why does a calculator show −1.6359 for cot 56?

The calculator is in radian mode (RAD): it takes cot 56 as the cotangent of 56 radians, cot 56 rad ≈ −1.6359. Switch it to degrees (DEG): cot 56° ≈ 0.6745. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
