Sin 46 Degrees
Sin, Cos, Tan, Cot of an Angle
What is sin 46°?
Answer
sin 46° ≈
0.7193
Angle in radians: 46° = 23π/90. The point of the angle is in quadrant I, where sine is positive.
≈ — rounded to 4 decimal places. sin 46° can't be written with square roots: 46° is not a multiple of 3°.
P(cos 46°, sin 46°) ≈ (0.6947, 0.7193)
P(cos 46°, sin 46°) ≈ (0.6947, 0.7193)
Highlighted: the projection on the y-axis — sine, y ≈ 0.7193.

FAQ
What is sin 46°?
sin 46° ≈ 0.7193
Why does sin 46° 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°. 46° is not, so no such exact form exists; the value is used as a decimal: sin 46° ≈ 0.7193.
Why does a calculator show 0.9018 for sin 46?
The calculator is in radian mode (RAD): it takes sin 46 as the sine of 46 radians, sin 46 rad ≈ 0.9018. Switch it to degrees (DEG): sin 46° ≈ 0.7193. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
