Subtract full rotations of 2π 2 π until the angle is greater than or equal to 0 0 and less than 2π 2 π. The exact value of sin(0) sin (0) is 0 0. Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor.

What is Sin of 2pi? The value of sin of 2pi is 0. i.e., sin 2 π = 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.

$$\sin{\frac{3 \pi}{7}} = \sin{\frac{4 \pi}{7}}$$ Using a combination of double-angle forumlae, we end up with a cubic equation for $\cos{(\pi/7)}$: $$8 \cos^3{\frac{\pi}{7}} - 4 \cos^2{\frac{\pi}{7}} - 4 \cos{\frac{\pi}{7}}+1=0$$

The result can be shown in multiple forms. Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor.
