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 fourth quadrant. −sin(15) - sin (15) Split 15 15 into two angles where the values of the six trigonometric functions are known. −sin(45− 30) - sin (45 - 30) Separate negation.

Sin 345 degrees in radians is written as sin (345° × π/180°), i.e., sin (23π/12) or sin (6.021385. . .). In this article, we will discuss the methods to find the value of sin 345 degrees with examples.

Nov 18, 2020 · To find the exact value of sin(345°), we can use the reference angle concept and the periodicity of the sine function. First, we find the reference angle by subtracting 360° from 345°, giving us 345° - 360° = -15°. Since the sine function is negative in the third quadrant, we have sin(-15°) = -sin(15°).

First, split the angle into two angles where the values of the six trigonometric functions are known. In this case, 345 345 can be split into 300+45 300 + 45. sin(300+45) sin (300 + 45) Use the sum formula for sine to simplify the expression.

Use our sin (x) calculator to find the sine of 345 degrees - sin (345 °) - or the sine of any angle in degrees and in radians.

What is the value of sin (345) ?

Calculate sin(345) sin is found using Opposite/Hypotenuse. Determine quadrant: Since 270 345 360 degrees it is located in Quadrant IV. cos is positive. Determine angle type: 345 > 90°, so it is obtuse. sin(345) = -0.25881905174851. Special Angle Values

To find the exact value of sin(345 degrees), we can use the fact that the sine function has periodicity of 360 degrees. Therefore, we can express sin(345 degrees) as sin(345 degrees - 360 degrees). This is equivalent to sin(-15 degrees).
