Tan 43 Degrees
Sin, Cos, Tan, Cot of an Angle
What is tan 43°?
Answer
tan 43° ≈
0.9325
Angle in radians: 43° = 43π/180. The point of the angle is in quadrant I, where tangent is positive.
≈ — rounded to 4 decimal places. tan 43° can't be written with square roots: 43° is not a multiple of 3°.
tan 43° = sin 43° / cos 43° ≈ 0.9325
P(cos 43°, sin 43°) ≈ (0.7314, 0.6820)
T(1, tan 43°) ≈ (1, 0.9325) — where line OP meets the line x = 1.

FAQ
What is tan 43°?
tan 43° ≈ 0.9325
Why does tan 43° 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°. 43° is not, so no such exact form exists; the value is used as a decimal: tan 43° ≈ 0.9325.
Why does a calculator show −1.4984 for tan 43?
The calculator is in radian mode (RAD): it takes tan 43 as the tangent of 43 radians, tan 43 rad ≈ −1.4984. Switch it to degrees (DEG): tan 43° ≈ 0.9325. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
