1.

The period of `f(x)=(1)/(2){(| sinx|)/(cos x)+(|cos|)/(sinx)}`, isA. Statement-1 is True, Statement-2 is True, statement-2 is a correct explanation for the statement-1 .B. Statement-1 is True, Statement-2 is True, statement-2 is not a correct explanation for the statement-1 .C. Statement-1 is True, Statement-2 is False.D. Statement-1 is False , Statement-2 is True.

Answer» Correct Answer - B
We have.
`f(x)=(1)/(2)((|sin|)/(cosx)+(sinx)/(|cosx|))`
`impliesf(x)={{:(tanx,x in [0,pi//2)),(0,x in(pi//2,pi]),(-tanx,x in [pi,3pi//2)),(0,x in[3pi//2,2pi]):}`
Clearly , f(x) is preiodic with period ` 2pi`.
So, Statement-1 is ture. Also , Statement-2 is true.
