Tan 47 Degrees
Sin, Cos, Tan, Cot of an Angle
What is tan 47°?
Answer
tan 47° ≈
1.0724
Angle in radians: 47° = 47π/180. The point of the angle is in quadrant I, where tangent is positive.
≈ — rounded to 4 decimal places. tan 47° can't be written with square roots: 47° is not a multiple of 3°.
tan 47° = sin 47° / cos 47° ≈ 1.0724
P(cos 47°, sin 47°) ≈ (0.6820, 0.7314)
T(1, tan 47°) ≈ (1, 1.0724) — where line OP meets the line x = 1.

FAQ
What is tan 47°?
tan 47° ≈ 1.0724
Why does tan 47° 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°. 47° is not, so no such exact form exists; the value is used as a decimal: tan 47° ≈ 1.0724.
Why does a calculator show −0.1245 for tan 47?
The calculator is in radian mode (RAD): it takes tan 47 as the tangent of 47 radians, tan 47 rad ≈ −0.1245. Switch it to degrees (DEG): tan 47° ≈ 1.0724. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
