In terms trigonometric functions, 2π is equivalent to 0. Based on the unit circle an angle of 0 has its terminal point on the positive X-axis ; the side opposite the angle has a length of 0 (and the adjacent side has a length of 1) tan 2pi=0 You can use the period of the trigonometric function to reduce 2pi to 0, so you have tan 2pi=tan 0 To 3/2 pi = ° = rad = - 1 / 2 π rad = grad = turns Basic knowledge of angle units The basic definition is that the full angle is 1 rotation (one turn) = ° (degrees) = 2π radians = grads (gons). One degree is 60 minutes and one angle minute is 60 seconds. see Plane angle - wiki Practice problems Trigonometry. 2π 3 2 π 3. To convert radians to degrees, multiply by π π, since a full circle is ° ° or 2π 2 π radians. (2π 3)⋅ ° π (2 π 3) ⋅ ° Step-by-Step Solution. Given that pi rad is equal to °, we can write the following radians to degrees conversion formula: α in degrees = α in π radians × /π, OR. α° = α rad × /π. Plugging the given angle value, in radians, in the previous formula, we get: α° = (π/2 × /π) = 90 degrees. Using our 'radians to degrees Trigonometry. 2π 6 2 π 6.

Let $\zeta$ be the n-th primitive unit root. with not too much effort I have proved that $\cos(2\pi /n)$ has degree $\varphi (n)/2$ over $\mathbb{Q}$, but failed to the degree of $\sin(2\pi /n)$ over $\mathbb{Q}$. I can myself only proof that $\sin(2\pi /n)=(\zeta -{{\zeta }^{-1}})/2i$, but don't know how to proceed. I am waiting for your help Popular Problems. Trigonometry. 2π 9 2 π 9.
