What is cot 50°?

Answer

cot 50° ≈
0.8391

Angle in radians: 50° = 5π/18. The point of the angle is in quadrant I, where cotangent is positive.

≈ — rounded to 4 decimal places. cot 50° can't be written with square roots: 50° is not a multiple of 3°.

cot 50° = cos 50° / sin 50° ≈ 0.8391

xyOP

P(cos 50°, sin 50°) ≈ (0.6428, 0.7660)

C(cot 50°, 1) ≈ (0.8391, 1) — where line OP meets the line y = 1.

FAQ

What is cot 50°?

cot 50° ≈ 0.8391

Why does cot 50° 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°. 50° is not, so no such exact form exists; the value is used as a decimal: cot 50° ≈ 0.8391.

Why does a calculator show −3.6778 for cot 50?

The calculator is in radian mode (RAD): it takes cot 50 as the cotangent of 50 radians, cot 50 rad ≈ −3.6778. Switch it to degrees (DEG): cot 50° ≈ 0.8391. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
