What is tan 35°?

Answer

tan 35° ≈
0.7002

Angle in radians: 35° = 7π/36. The point of the angle is in quadrant I, where tangent is positive.

≈ — rounded to 4 decimal places. tan 35° can't be written with square roots: 35° is not a multiple of 3°.

tan 35° = sin 35° / cos 35° ≈ 0.7002

P(cos 35°, sin 35°) ≈ (0.8192, 0.5736)

T(1, tan 35°) ≈ (1, 0.7002) — where line OP meets the line x = 1.

FAQ

What is tan 35°?

tan 35° ≈ 0.7002

Why does tan 35° 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°. 35° is not, so no such exact form exists; the value is used as a decimal: tan 35° ≈ 0.7002.

Why does a calculator show 0.4738 for tan 35?

The calculator is in radian mode (RAD): it takes tan 35 as the tangent of 35 radians, tan 35 rad ≈ 0.4738. Switch it to degrees (DEG): tan 35° ≈ 0.7002. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
