Sin 210 degrees in radians is written as sin (210° × π/180°), i.e., sin (7π/6) or sin (3.665191. . .). In this article, we will discuss the methods to find the value of sin 210 degrees with examples.

Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because sine is negative in the third quadrant. The exact value of sin(30) sin (30) is 1 2 1 2. The result can be shown in multiple forms.

Use our sin(x) calculator to find the exact value of sine of 210 degrees - sin(210 °) - or the sine of any angle in degrees and in radians.
