What is Cot 5pi/3? Cot 5pi/3 is the value of cotangent trigonometric function for an angle equal to 5π/3 radians. The value of cot 5pi/3 is -(1/√3) or -0.5774 (approx).

How do you find the value of tan15?

Tan (15°) can be found if we know the value of sin 15 degrees and cos 15 degrees. …
From the above table, we have the values of tan, sin and cos ratios for 0°, 30°, 45°, 60° and 90°. …
tan (15°) = √3 – 1/ √3 + 1.
Hence, the value of tan (15°) is √3 – 1/√3 + 1.
∴ Tan (15°) = (1.732 – 1)/(1.732 + 1) = 0.2679.

How do you find the value of cot?

In a right triangle, the cotangent of an angle is the length of the adjacent side divided by the length of the opposite side. In a formula, it is abbreviated to just ‘cot’.
