 Hi and welcome to the session. I'm Priyanka and let us discuss the following questions with you. Find the values of the trigonometric functions i.e. tan 19 pi by 3. We know that the values of retrieve an interval right. So therefore we can write tan 19 pi by 3 as i plus pi by 3, isn't it? Because on survey we will get 19 pi by 3. It can be further written as tan pi by 3. And the value of tan pi by 3 is equal to what exactly is equal to root 3. So this is our final answer. I hope you enjoyed this session. Take care of your calculations. Remember the values by some others.
