What is tan 29°?

Answer

tan 29° ≈
0.5543

Angle in radians: 29° = 29π/180. The point of the angle is in quadrant I, where tangent is positive.

≈ — rounded to 4 decimal places. tan 29° can't be written with square roots: 29° is not a multiple of 3°.

tan 29° = sin 29° / cos 29° ≈ 0.5543

P(cos 29°, sin 29°) ≈ (0.8746, 0.4848)

T(1, tan 29°) ≈ (1, 0.5543) — where line OP meets the line x = 1.

FAQ

What is tan 29°?

tan 29° ≈ 0.5543

Why does tan 29° 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°. 29° is not, so no such exact form exists; the value is used as a decimal: tan 29° ≈ 0.5543.

Why does a calculator show 0.8871 for tan 29?

The calculator is in radian mode (RAD): it takes tan 29 as the tangent of 29 radians, tan 29 rad ≈ 0.8871. Switch it to degrees (DEG): tan 29° ≈ 0.5543. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
