What is cot 73°?

Answer

cot 73° ≈
0.3057

Angle in radians: 73° = 73π/180. The point of the angle is in quadrant I, where cotangent is positive.

≈ — rounded to 4 decimal places. cot 73° can't be written with square roots: 73° is not a multiple of 3°.

cot 73° = cos 73° / sin 73° ≈ 0.3057

xyOP

P(cos 73°, sin 73°) ≈ (0.2924, 0.9563)

C(cot 73°, 1) ≈ (0.3057, 1) — where line OP meets the line y = 1.

FAQ

What is cot 73°?

cot 73° ≈ 0.3057

Why does cot 73° 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°. 73° is not, so no such exact form exists; the value is used as a decimal: cot 73° ≈ 0.3057.

Why does a calculator show 1.0878 for cot 73?

The calculator is in radian mode (RAD): it takes cot 73 as the cotangent of 73 radians, cot 73 rad ≈ 1.0878. Switch it to degrees (DEG): cot 73° ≈ 0.3057. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
