If `lim_(x rarr 0) ((cos 4x + a cos 2x + b)/x^4)` is finite then the value of `a, b` respectively

If lim_(x rarr 0) ((cos 4x + a cos 2x+b)/(x^(4))) is finite, then the values of a and b are respectively.

If lim_(x rarr0)(cos4x+a cos2x+b)/(x^(4)) is finite then the value of a,b respectively

If lim_(x rarr 0) (cos4x+a cos2x+b)/x^4 is finite then the value of a,b respectively

Lt_(x to 0) ((cos4x+a cos 3x+b)/(x^(4))) is finite then the values of a,b are respectively

If underset(x to 0)"Lt" ((cos 4x+a cos 2x+b)/(x^(4))) is finite, then the value of a, b are respectiveluy.

lim_(x rarr0)[cos x]is

lim_(x rarr0)(cos x)/(x+2)

lim_(x rarr0)(cos x)/(x+2)

If lim_(x rarr0)(a cos x+bx sin x-5)/(x^(4)) is finite the a=
