What is cot 26°?

Answer

cot 26° ≈
2.0503

Angle in radians: 26° = 13π/90. The point of the angle is in quadrant I, where cotangent is positive.

≈ — rounded to 4 decimal places. cot 26° can't be written with square roots: 26° is not a multiple of 3°.

cot 26° = cos 26° / sin 26° ≈ 2.0503

P(cos 26°, sin 26°) ≈ (0.8988, 0.4384)

C(cot 26°, 1) ≈ (2.0503, 1) — where line OP meets the line y = 1; C is beyond the drawing, the arrow points to it.

FAQ

What is cot 26°?

cot 26° ≈ 2.0503

Why does cot 26° 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°. 26° is not, so no such exact form exists; the value is used as a decimal: cot 26° ≈ 2.0503.

Why does a calculator show 0.8484 for cot 26?

The calculator is in radian mode (RAD): it takes cot 26 as the cotangent of 26 radians, cot 26 rad ≈ 0.8484. Switch it to degrees (DEG): cot 26° ≈ 2.0503. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
