Tan 73 Degrees
Sin, Cos, Tan, Cot of an Angle
What is tan 73°?
Answer
tan 73° ≈
3.2709
Angle in radians: 73° = 73π/180. The point of the angle is in quadrant I, where tangent is positive.
≈ — rounded to 4 decimal places. tan 73° can't be written with square roots: 73° is not a multiple of 3°.
tan 73° = sin 73° / cos 73° ≈ 3.2709
P(cos 73°, sin 73°) ≈ (0.2924, 0.9563)
T(1, tan 73°) ≈ (1, 3.2709) — where line OP meets the line x = 1; T is beyond the drawing, the arrow points to it.

FAQ
What is tan 73°?
tan 73° ≈ 3.2709
Why does tan 73° 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°. 73° is not, so no such exact form exists; the value is used as a decimal: tan 73° ≈ 3.2709.
Why does a calculator show 0.9193 for tan 73?
The calculator is in radian mode (RAD): it takes tan 73 as the tangent of 73 radians, tan 73 rad ≈ 0.9193. Switch it to degrees (DEG): tan 73° ≈ 3.2709. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
