WebJul 9, 2024 · The reference angle of is Step-by-step explanation: Given Required Which represent its reference angle The very first step is to determine the quadrant of the given … WebThe value of sin of 2pi is 0. i.e., sin 2π = 0. From trigonometric table, we know the trigonometric ratios of standard angles 0, π/6, π/4, π/3, and π/2.So this table doesn't give us the value of sin of 2pi. Usually, to find the value of any trigonometric ratio of a non-standard angle, we use the reference angles and the quadrant in which the angle lies in.
