What is cos 14°?

Answer

cos 14° ≈
0.9703

Angle in radians: 14° = 7π/90. The point of the angle is in quadrant I, where cosine is positive.

≈ — rounded to 4 decimal places. cos 14° can't be written with square roots: 14° is not a multiple of 3°.

P(cos 14°, sin 14°) ≈ (0.9703, 0.2419)

FAQ

What is cos 14°?

cos 14° ≈ 0.9703

Why does cos 14° 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°. 14° is not, so no such exact form exists; the value is used as a decimal: cos 14° ≈ 0.9703.

Why does a calculator show 0.1367 for cos 14?

The calculator is in radian mode (RAD): it takes cos 14 as the cosine of 14 radians, cos 14 rad ≈ 0.1367. Switch it to degrees (DEG): cos 14° ≈ 0.9703. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
