 Hi and welcome to the session. I am Deepika here. Let's discuss the question if sin inverse x is equal to y then a 0 is less than equal to y, y is less than equal to pi b minus pi by 2 is less than equal to y, y is less than equal to pi by 2, c 0 is less than strictly less than y and it is strictly less than pi b minus pi by 2 is less than y and y is less than pi by 2. So, let's start the solution principal value branch by 2, 2 pi by 2 y equal to y, y is less than equal to pi by 2 and which is our option b, our question is that the question is clear to you, find and enjoy yourself.
