Tan 2pi/3 is the value of tangent trigonometric function for an angle equal to 2π/3 radians. The value of tan 2pi/3 is -√3 or -1.7321 (approx).

What is the exact value of tan 2pi?

The value of tan 2pi is 0. Tan 2pi radians in degrees is written as tan ((2π) × 180°/π), i.e., tan (360°).

What is Sinpi?

Sin pi is the value of sine trigonometric function for an angle equal to pi radians. The value of sin pi is 0.

What is the value 2π?

There are 2π radians in a full circle. (So 2π radians should equal 360°. Check it out by multiplying 57.30° by 2π = 6.283.

Is the sin of pi zero?

What is the value of sin pi? In trigonometry, we use pi (π) for 180 degrees to represent the angle in radians. Hence, sin π is equal to sin 180 or sin π = 0.

What value of secant is 2pi 3?

Trigonometry Examples

The exact value of sec(π3) sec ( π 3 ) is 2 . Multiply −1 by 2 .

How do you find the cot of 2pi 3?

Cot 2pi/3 radians in degrees is written as cot ((2π/3) × 180°/π), i.e., cot (120°).

We can use trigonometric identities to represent cot 2pi/3 as,
tan (pi/2 – 2pi/3) = tan(-pi/6)-tan (pi/2 + 2pi/3) = -tan 7pi/6.-cot (pi – 2pi/3) = -cot pi/3.

What is SEC 2x?

Explanation: sec(2x) = 1cos(2x) = 1cos(x+x) = 1cosx⋅cosx+sinx⋅sinx [Expanded using addition identity]
