Cos 44 Degrees
Sin, Cos, Tan, Cot of an Angle
What is cos 44°?
Answer
cos 44° ≈
0.7193
Angle in radians: 44° = 11π/45. The point of the angle is in quadrant I, where cosine is positive.
≈ — rounded to 4 decimal places. cos 44° can't be written with square roots: 44° is not a multiple of 3°.
P(cos 44°, sin 44°) ≈ (0.7193, 0.6947)
P(cos 44°, sin 44°) ≈ (0.7193, 0.6947)
Highlighted: the projection on the x-axis — cosine, x ≈ 0.7193.

FAQ
What is cos 44°?
cos 44° ≈ 0.7193
Why does cos 44° 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°. 44° is not, so no such exact form exists; the value is used as a decimal: cos 44° ≈ 0.7193.
Why does a calculator show 0.9998 for cos 44?
The calculator is in radian mode (RAD): it takes cos 44 as the cosine of 44 radians, cos 44 rad ≈ 0.9998. Switch it to degrees (DEG): cos 44° ≈ 0.7193. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
