 Hello and welcome to the session. Let us understand the following problem. Find the value of tan inverse of tan 7 pi by 6. Let us write the solution. Tan inverse of tan 7 pi by 6 is equal to tan inverse of tan of pi plus pi by 6 which is equal to tan inverse of tan pi by 6 because tan of pi plus theta is equal to tan theta which is equal to pi by 6. Therefore, the required answer is pi by 6. I hope you understood this session by Anonize Day.
