In the second last step where are terms like (3/2)^x and (2/3)^x ?
It get cancelled
I minimize it
Ans of question 1 is 1
It is B
Can you explain, I did not understood.
I solved 2.. did not realise at first how to do that problem.
Can you help me with other problems?
In that step, shouldn't it be (mod A)^2 = -1 ?
Think a little bit can a squared quantity be equal to a negative when we are taking about all real
That is true.. but that does not mean we will make it positive, I think so.
When I think about it I think there is error in my solution
For question 3:
A simple observation can solve this problem
we know that
So at any cost there is no sinx(I meant sinx to the power 1)in the matrix itself
So Obviously in the expansion of determinant there won't be any sinx term at all
Hence a_1=0 is the right answer.
Any doubts, do let me know
Yes, that is the right answer.
Sorry, I forgot to tell but it is multicorrect answer.
In question 3, answer is ABC.
There is no chance for a_0 to be zero.
Because if you write the entire matrix in terms of sinx
