In this question we have two statements and based on the statements we need to decide which option is correct.
00:07
Statement 1 says that argument minus 1 plus i root 3 into minus 2 plus 2i into i is equal to minus pi by 12.
00:34
Statement 2 says that argument z1, z2, z3 is equal to argument z1, argument z2 plus argument z3.
01:04
Let's see how to solve this question.
01:07
Statement second is true since it is a property and we know that argument z1, z2, z2, z3 is equals to argument z1 plus argument z2 plus argument z3.
01:36
Now statement 1, we know that argument minus 1 plus i root 3 can be written as 2 pi by 3.
01:53
Argument minus 2 plus 2i can be written as 3 pi by 4 and argument i can be written as pi by 2.
02:14
Substitute all these values as given in the statement 1.
02:19
So what we get? we get argument of the product...
