What is tan 341°?

Answer

tan 341° ≈
−0.3443

Angle in radians: 341° = 341π/180. The point of the angle is in quadrant IV, where tangent is negative.

≈ — rounded to 4 decimal places. tan 341° can't be written with square roots: 341° is not a multiple of 3°.

tan 341° = tan(360° − 19°) = −tan 19° ≈ −0.3443

tan 341° = sin 341° / cos 341° ≈ −0.3443

xyOP

P(cos 341°, sin 341°) ≈ (0.9455, −0.3256)

T(1, tan 341°) ≈ (1, −0.3443) — where line OP meets the line x = 1.

FAQ

What is tan 341°?

tan 341° ≈ −0.3443

Why does tan 341° 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°. 341° is not, so no such exact form exists; the value is used as a decimal: tan 341° ≈ −0.3443.

Why does a calculator show −7.2430 for tan 341?

The calculator is in radian mode (RAD): it takes tan 341 as the tangent of 341 radians, tan 341 rad ≈ −7.2430. Switch it to degrees (DEG): tan 341° ≈ −0.3443. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
