 Hello and welcome to the session I am Deepika here let's discuss a question find the principal value of cosecant inverse 2 now we know that the range of the principal value branch of cosecant inverses grows interval minus pi by 2 to pi by 2 excluding 0 so let's start the solution cosecant inverse equal to y then then cosecant phi is equal to 2 and which is equal to cosecant pi by 6 the variable value branch of inverse is pi by 2 to pi by 2 and excluding 0 second pi by 6 equal to 2 therefore the principal value of cosecant inverse pi by 6 so this is the answer for the above question I hope the question is clear to you bye and enjoy yourself
