Cot 88 Degrees
Sin, Cos, Tan, Cot of an Angle
What is cot 88°?
Answer
cot 88° ≈
0.0349
Angle in radians: 88° = 22π/45. The point of the angle is in quadrant I, where cotangent is positive.
≈ — rounded to 4 decimal places. cot 88° can't be written with square roots: 88° is not a multiple of 3°.
cot 88° = cos 88° / sin 88° ≈ 0.0349
P(cos 88°, sin 88°) ≈ (0.0349, 0.9994)
C(cot 88°, 1) ≈ (0.0349, 1) — where line OP meets the line y = 1.

FAQ
What is cot 88°?
cot 88° ≈ 0.0349
Why does cot 88° 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°. 88° is not, so no such exact form exists; the value is used as a decimal: cot 88° ≈ 0.0349.
Why does a calculator show 28.2322 for cot 88?
The calculator is in radian mode (RAD): it takes cot 88 as the cotangent of 88 radians, cot 88 rad ≈ 28.2322. Switch it to degrees (DEG): cot 88° ≈ 0.0349. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
