    Graphs of \[y=\sin x\] and\[y=\cos x\], where \[0\le x\le \frac{\pi }{2}\]intersect at a point. Find abscissa.

    A)   \[\frac{\pi }{6}\]                            

    B)  \[\frac{\pi }{4}\]   

    C)  \[\frac{\pi }{3}\]             

    D)         0

    Correct Answer: B

    Solution :

     When\[\Rightarrow \] \[x=\frac{5040\times 12}{144}=420\] \[219\times =657\]The graphs intersect at\[3\times =219\].
