 Hi and how are you all today? Let us start with the question. It says find the principle and the general solution of the following equation. Now the value of cossack x is given to us as minus 2. Let us start with our solution. Now first of all we need to think that if we are given the value of cossack x as negative that means x lies in third and fourth quadrant, right? So let us find out the value of cossack in the third and the fourth quadrant. Cossack x is equal to minus 2 is equal to cossack plus pi by 6. Since it is in the third quadrant we will be adding it to pi to make it in the third quadrant and it comes out to be cossack 7 pi by 6, right? Similarly we will be finding the value of cossack x in the fourth quadrant. So that will be cossack. Now it will be 2 pi minus pi by 6 as it is in the fourth quadrant will be subtracting it from 2 pi and the answer comes out to be cossack 11 pi by 6, right? So that means the principle solution of x in the third quadrant is 7 pi by 6 and in the fourth quadrant it is 11 pi by 6, right? Proceeding on to find the general solution it will be x is equal to as cossack x is equal to 1 by sine x that means x is never equal to n pi. So it will be n pi plus minus 1 to the power n y that will be 7 pi by 6 and this is the general solution in case of cossack x where we write it as x is equal to n pi plus minus 1 to the power n and we will include y in it where y is 7 pi by 6 and also where n belongs to the set of integers, right? So this answers the question that was given to us. I hope you enjoyed the session and do remember how to find out the principle solution and the general solution. Bye for now.
