" If "y=log tan((pi)/(4)+(x)/(2))," then "(dy)/(dx)" is "

If y=log tan((pi)/(4)+(x)/(2)), show that (dy)/(dx)=sec x. Also find the value of (d^(2)y)/(dx^(2)) at x=(pi)/(4)

(d)/(dx)(log tan((pi)/(4)+(x)/(2)))=

(d)/(dx)(log tan((pi)/(4)+(x)/(2)))=

Let y=tan((pi)/4+x/2) . Then (dy)/(dx) at x=(pi)/4

Let y=tan((pi)/4+x/2) . Then (dy)/(dx) at x=(pi)/4
