Let f(x) be a polynomial of least degree such that lim_(x rarr0)(1+(x^(4)+f(x^(2)))/(x^(3)))^(1/x)=e^(3), then write the value of f(3)

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

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

lim_(x rarr0)(log(1-(x)/(2)))/(x)

lim_(x rarr0)(1+2x)^(5/x)

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

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