underset(x rarr 0)(lim) (cos 4x - 4 cos 2x + 3)/(x^(4)) =

underset( x rarr 0 ) ( "Lim") ((x- 1+ cos x )/( x))^((1)/( x))

If l = underset( x rarr 0) ("Lim")( x ( 1+ a cos x ) - bsin x ) /( x^(3))= underset( x rarr 0 ) ("Lim") ( 1+a cos x ) /( x^(2))- underset( x rarr 0 ) ("lim")( b sin x )/( x^(3)) , where l in R , then

lim_(x rarr0)(1-cos3x)/(x^(2))

lim_(x rarr0)(cos3x-cos5x)/(x^(2))

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

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