" i) "quad (y)=tan x+sec x;(d^(2)y)/(dx^(2))=(cos x)/((1-sin x)^(2))

If y=tan x+sec x, prove that (d^(2)y)/(dx^(2))=(cos x)/((1-sin x)^(2))

If y=tan X+sec x, prove that (d^(2)y)/(dx^(2))=(cos x)/((1-sin x)^(2))

y=tan x+sec x. Prove that (d^2y)/(dx^2)=cosx/((1+sinx)^2 .

If y = tan x + sec x , prove that (d^2y)/(dx^2) = (cosx)/((1-sinx)^2)

if y = tan x + sec x, prove that (d ^ (2) y) / (dx ^ (2)) = (cos x) / ((1-sin x) ^ (2))

If y=sec x -tan x ,then (d^(2)y)/(dx^(2)) =

"If "y=(2)/(sqrt(a^(2)-b^(2))){tan^(-1)(sqrt((a-b)/(a+b))tan""(x)/(2))}," then show that "(d^(2)y)/(dx^(2))=(b sin x)/((a+b cos x)^(2)).

If y= sin x+cos x then (d^(2)y)/(dx^(2)) is :-

If y= sin x+cos x then (d^(2)y)/(dx^(2)) is :-
