" fe "y-log tan((pi)/(4)+(x)/(2))," at firs "(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)

(dy)/(dx)+y sec x=tan x

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

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

(dy)/(dx)+y tan x=sec x

(d)/(dx)(log tan((pi)/(4)+(x)/(2)))= (a) cosec x (b) -cosec x (c) sec x (d) -sec x

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=(tan x)^(log x)+cos^(2)((pi)/(4)), find (dy)/(dx)
