Go with beta function these r application of beta function
#15 Its king and add property ans will be 9
No its neither odd nor even
[x]+[-x]= -1 piece wise defined function it may be zero also
#16 try to make perfect square then u will the results
So, what's your approach for Q 17
Same even odd property take common u will get result i mean king property
see a=0 directly satisfies the inequalitiy....
Now the take given integrand as f(x) now clearly a<0 and the integration will be less than zero only amd only if graph of f(x) is below x axis ...
Now f(0) = -1 and f(-1) is 63 and f'(x) <0 for x <0 hence monotonic
therefore f(x) is zero for some m E(-1,0) and f(x) will be above y axis for values less than m .....therefore there is no otjer integral value of a to satisfy the inequality ......
hence ans is (B) 1
Ask me if u have any queries in sol
