Sin 175 Degrees
Sin, Cos, Tan, Cot of an Angle
What is sin 175°?
Answer
sin 175° ≈
0.0872
Angle in radians: 175° = 35π/36. The point of the angle is in quadrant II, where sine is positive.
≈ — rounded to 4 decimal places. sin 175° can't be written with square roots: 175° is not a multiple of 3°.
sin 175° = sin(180° − 5°) = sin 5° ≈ 0.0872
P(cos 175°, sin 175°) ≈ (−0.9962, 0.0872)
P(cos 175°, sin 175°) ≈ (−0.9962, 0.0872)
Highlighted: the projection on the y-axis — sine, y ≈ 0.0872.

FAQ
What is sin 175°?
sin 175° ≈ 0.0872
Why does sin 175° 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°. 175° is not, so no such exact form exists; the value is used as a decimal: sin 175° ≈ 0.0872.
Why does a calculator show −0.8011 for sin 175?
The calculator is in radian mode (RAD): it takes sin 175 as the sine of 175 radians, sin 175 rad ≈ −0.8011. Switch it to degrees (DEG): sin 175° ≈ 0.0872. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
