Cot 25 Degrees
Sin, Cos, Tan, Cot of an Angle
What is cot 25°?
Answer
cot 25° ≈
2.1445
Angle in radians: 25° = 5π/36. The point of the angle is in quadrant I, where cotangent is positive.
≈ — rounded to 4 decimal places. cot 25° can't be written with square roots: 25° is not a multiple of 3°.
cot 25° = cos 25° / sin 25° ≈ 2.1445
P(cos 25°, sin 25°) ≈ (0.9063, 0.4226)
C(cot 25°, 1) ≈ (2.1445, 1) — where line OP meets the line y = 1; C is beyond the drawing, the arrow points to it.

FAQ
What is cot 25°?
cot 25° ≈ 2.1445
Why does cot 25° 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°. 25° is not, so no such exact form exists; the value is used as a decimal: cot 25° ≈ 2.1445.
Why does a calculator show −7.4892 for cot 25?
The calculator is in radian mode (RAD): it takes cot 25 as the cotangent of 25 radians, cot 25 rad ≈ −7.4892. Switch it to degrees (DEG): cot 25° ≈ 2.1445. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
