Discuss the continuity of the function f(x) ={:{((1+cos x)/(tan^2 x) ", "x ne pi),((1)/(2) ", " x=pi):}, at =pi .

f (x) = {(cos x) / ((pi) / (2) -x), x! = (pi) / (2) 1, x = (pi) / (2)

lim_ (x rarr pi) (1 + cos x) / (tan ^ (2) x)

lim_ (x rarr pi) ((1 + cos x) / (tan ^ (2) x))

If f(x)=cos^(2)x*e^(tan x),x in(-(pi)/(2),(pi)/(2)) ,then

f(x)={tan^(-1)x,|x|<(pi)/(4) and (pi)/(2)-|x|,|x|<=(pi)/(4)

f(x)= |(sin x,cos x),(tan x,cot x)| then f'((pi)/(4)) = …….
