# Find the values of the trigonometric functions in Exercises 6 to 10:

8. tan 19 π / 3

**Solution:**

It can be written as

tan 19 π / 3 = tan [ 3 (2π) + π / 3 ]

We know that the values of tan x (any trigonometric function) repeat after an interval of 360° or 2π.

⇒ tan 19 π / 3 = tan π / 3

⇒ tan 19 π / 3 = tan 60 °

⇒ tan 19 π / 3 = √ 3 (Using trigonometric table)
