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

lim_(x rarr0)(1-cos2x)/(3tan^(2)x)

lim_(x rarr0)(cos x)/(pi-x)

if L=lim_(x rarr pi)(tan(pi cos^(2)x))/((x-pi)^(2)) then (L)/(pi) is equal to:

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

Lim_(x rarr pi/2)(cos x)/((pi)/(2)-x)

lim_ (x rarr pi) (1 + cos x) / (x-pi)

lim_(x rarr 0) ((x)/(tan^(-1) 2x)) is :

For a in R^(+) such that lim_(x rarr0)(1-cos ax)/(x^(2))=lim_(x rarr pi)(sin x)/(pi-x) then a=

For a in R^(+) such that lim_(x rarr0)(1-cos ax)/(x^(2))=lim_(x rarr pi)(sin x)/(pi-x) then the value of a is
