Tan 355 Degrees
Sin, Cos, Tan, Cot of an Angle
What is tan 355°?
Answer
tan 355° ≈
−0.0875
Angle in radians: 355° = 71π/36. The point of the angle is in quadrant IV, where tangent is negative.
≈ — rounded to 4 decimal places. tan 355° can't be written with square roots: 355° is not a multiple of 3°.
tan 355° = tan(360° − 5°) = −tan 5° ≈ −0.0875
tan 355° = sin 355° / cos 355° ≈ −0.0875
P(cos 355°, sin 355°) ≈ (0.9962, −0.0872)
T(1, tan 355°) ≈ (1, −0.0875) — where line OP meets the line x = 1.

FAQ
What is tan 355°?
tan 355° ≈ −0.0875
Why does tan 355° 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°. 355° is not, so no such exact form exists; the value is used as a decimal: tan 355° ≈ −0.0875.
Why does a calculator show 0.0000301 for tan 355?
The calculator is in radian mode (RAD): it takes tan 355 as the tangent of 355 radians, tan 355 rad ≈ 0.0000301. Switch it to degrees (DEG): tan 355° ≈ −0.0875. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
