What is cot 49°?

Answer

cot 49° ≈
0.8693

Angle in radians: 49° = 49π/180. The point of the angle is in quadrant I, where cotangent is positive.

≈ — rounded to 4 decimal places. cot 49° can't be written with square roots: 49° is not a multiple of 3°.

cot 49° = cos 49° / sin 49° ≈ 0.8693

xyOP

P(cos 49°, sin 49°) ≈ (0.6561, 0.7547)

C(cot 49°, 1) ≈ (0.8693, 1) — where line OP meets the line y = 1.

FAQ

What is cot 49°?

cot 49° ≈ 0.8693

Why does cot 49° 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°. 49° is not, so no such exact form exists; the value is used as a decimal: cot 49° ≈ 0.8693.

Why does a calculator show −0.3152 for cot 49?

The calculator is in radian mode (RAD): it takes cot 49 as the cotangent of 49 radians, cot 49 rad ≈ −0.3152. Switch it to degrees (DEG): cot 49° ≈ 0.8693. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
