`lim_(x rarr 0) (2(1-cosx))/x^2`

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

lim_(x rarr0)(1-cos x)/(x^(2))

Evaluate the following limits : lim_(x rarr 0) (1-cosx)/((e^(x^2)-1))

lim_(x rarr 0) (e^(x^2)-cosx)/x^2 =

lim_(x rarr0)(1-cos x^(@))/(x^(2))

The value of lim_(x rarr 0) (1-cos(1-cosx))/(x^(4)) is

lim_(x rarr0)(1-cos mx)/(x^(2))

lim_(x rarr0)([(2(cosh x-1))/(x^(2))]^(1))/(x^(2))

a=lim_(x rarr0)(ln(cos2x))/(3x^(2)),b=lim_(x rarr0)(sin^(2)2x)/(x(1-e^(x))),c=lim_(x rarr1)(sqrt(x)-x)/(ln x)

lim_(x rarr0)(sin^2x)/(1-cosx)
