" 30."quad " If "y=log tan((pi)/(4)+(x)/(2))," show that "(dy)/(dx)-sec x=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) , show that: dy/dx-secx=0

If y=log sqrt((1+tan x)/(1-tan x)), Prove that (dy)/(dx)=sec2x

If y=log sqrt((1-tan x)/(1+tan x)), prove that (dy)/(dx)=sec2x

If y=sqrt((1-sin2x)/(1+sin2x)) , show that dy/dx+sec^2(pi/4-x)=0

is y=sqrt((1-sin2x)/(1+sin2x)), show that (dy)/(dx)+sec^(2)((pi)/(4)-x)=0

y = log sec(pi/4 + x/2), show that dy/dx=1/2tan(pi/4+x/2)

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

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