Tan 22 Degrees
Sin, Cos, Tan, Cot of an Angle
What is tan 22°?
Answer
tan 22° ≈
0.4040
Angle in radians: 22° = 11π/90. The point of the angle is in quadrant I, where tangent is positive.
≈ — rounded to 4 decimal places. tan 22° can't be written with square roots: 22° is not a multiple of 3°.
tan 22° = sin 22° / cos 22° ≈ 0.4040
P(cos 22°, sin 22°) ≈ (0.9272, 0.3746)
T(1, tan 22°) ≈ (1, 0.4040) — where line OP meets the line x = 1.

FAQ
What is tan 22°?
tan 22° ≈ 0.4040
Why does tan 22° 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°. 22° is not, so no such exact form exists; the value is used as a decimal: tan 22° ≈ 0.4040.
Why does a calculator show 0.0089 for tan 22?
The calculator is in radian mode (RAD): it takes tan 22 as the tangent of 22 radians, tan 22 rad ≈ 0.0089. Switch it to degrees (DEG): tan 22° ≈ 0.4040. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
