**What is the exact value of tan 30?**<\/p>\n

The exact value of tan 30 is 0.577.<\/p>\n

Trigonometry is a branch of mathematics that deals with the relationships between angles and the sides of triangles. In trigonometry, the tangent function (tan) is used to determine the ratio of the length of the side opposite an angle to the length of the side adjacent to the angle. The value of the tangent function varies depending on the angle given. In the case of 30 degrees, the exact value of the tangent function can be calculated.<\/p>\n

To find the exact value of tan 30, we should first understand the concept of a special triangle called the 30-60-90 triangle. This triangle has angles measuring 30 degrees, 60 degrees, and 90 degrees. In this triangle, the side lengths follow a specific ratio. The shorter leg, opposite the 30-degree angle, is half the length of the hypotenuse, and the longer leg, opposite the 60-degree angle, is multiplied by the square root of 3.<\/p>\n

By using the properties of the 30-60-90 triangle, we can determine the exact value of tan 30. Since the tangent function is defined as the ratio of the opposite side (in this case, the shorter leg) to the adjacent side (the longer leg), we need to take the ratio of these two lengths. Given that the shorter leg is half the length of the hypotenuse, and the longer leg is the square root of 3 times the length of the shorter leg, we can calculate:<\/p>\n

tan 30 = Opposite \/ Adjacent
\n = (1\/2) \/ (\u221a3 * (1\/2))
\n = 1 \/ (\u221a3\/2)
\n = 2 \/ \u221a3<\/p>\n

To rationalize the denominator, we multiply both the numerator and the denominator by \u221a3:<\/p>\n

tan 30 = (2 \/ \u221a3) * (\u221a3 \/ \u221a3)
\n = 2\u221a3 \/ 3<\/p>\n

Therefore, the exact value of tan 30 is 2\u221a3 \/ 3, which is approximately 0.577. This means that the ratio of the length of the side opposite a 30-degree angle to the length of the side adjacent to it is approximately 0.577.<\/p>\n
