If `y=logtan(pi/4+x/2),\ ` show that `(dy)/(dx)=secxdot` Also find the value of `(d^2y)/(dx^2)` at `x=pi/4`

If y=logtan(pi/4+x/2) , show that : (dy)/(dx)-secx=0 .

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)

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

If y=e^(sin x) ,the value of (dy)/(dx) at x=(pi)/(2) is

If x = 3 tant and y = 3 sec t, then the value of (d^2y)/(dx^2)" at" t=pi/4 is

If y=|tanx-|sinx|| , then the value of (dy)/(dx) at x=(5pi)/(4) is

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