What is cot 2°?

Answer

cot 2° ≈
28.6363

Angle in radians: 2° = π/90. The point of the angle is in quadrant I, where cotangent is positive.

≈ — rounded to 4 decimal places. cot 2° can't be written with square roots: 2° is not a multiple of 3°.

cot 2° = cos 2° / sin 2° ≈ 28.6363

xyOP

P(cos 2°, sin 2°) ≈ (0.9994, 0.0349)

C(cot 2°, 1) ≈ (28.6363, 1) — where line OP meets the line y = 1; C is beyond the drawing, the arrow points to it.

FAQ

What is cot 2°?

cot 2° ≈ 28.6363

Why does cot 2° 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°. 2° is not, so no such exact form exists; the value is used as a decimal: cot 2° ≈ 28.6363.

Why does a calculator show −0.4577 for cot 2?

The calculator is in radian mode (RAD): it takes cot 2 as the cotangent of 2 radians, cot 2 rad ≈ −0.4577. Switch it to degrees (DEG): cot 2° ≈ 28.6363. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
