Cot 68 Degrees
Sin, Cos, Tan, Cot of an Angle
What is cot 68°?
Answer
cot 68° ≈
0.4040
Angle in radians: 68° = 17π/45. The point of the angle is in quadrant I, where cotangent is positive.
≈ — rounded to 4 decimal places. cot 68° can't be written with square roots: 68° is not a multiple of 3°.
cot 68° = cos 68° / sin 68° ≈ 0.4040
P(cos 68°, sin 68°) ≈ (0.3746, 0.9272)
C(cot 68°, 1) ≈ (0.4040, 1) — where line OP meets the line y = 1.

FAQ
What is cot 68°?
cot 68° ≈ 0.4040
Why does cot 68° 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°. 68° is not, so no such exact form exists; the value is used as a decimal: cot 68° ≈ 0.4040.
Why does a calculator show −0.4902 for cot 68?
The calculator is in radian mode (RAD): it takes cot 68 as the cotangent of 68 radians, cot 68 rad ≈ −0.4902. Switch it to degrees (DEG): cot 68° ≈ 0.4040. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
