Sin 88 Degrees
Sin, Cos, Tan, Cot of an Angle
What is sin 88°?
Answer
sin 88° ≈
0.9994
Angle in radians: 88° = 22π/45. The point of the angle is in quadrant I, where sine is positive.
≈ — rounded to 4 decimal places. sin 88° can't be written with square roots: 88° is not a multiple of 3°.
P(cos 88°, sin 88°) ≈ (0.0349, 0.9994)
P(cos 88°, sin 88°) ≈ (0.0349, 0.9994)
Highlighted: the projection on the y-axis — sine, y ≈ 0.9994.

FAQ
What is sin 88°?
sin 88° ≈ 0.9994
Why does sin 88° 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°. 88° is not, so no such exact form exists; the value is used as a decimal: sin 88° ≈ 0.9994.
Why does a calculator show 0.0354 for sin 88?
The calculator is in radian mode (RAD): it takes sin 88 as the sine of 88 radians, sin 88 rad ≈ 0.0354. Switch it to degrees (DEG): sin 88° ≈ 0.9994. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
