x^2
f(x) = ---------- - x^2
√(1+x^2)
g(x) = cos(x)sin(x^2) - x^2
compute the coefficients of x^4 and x^9 in the Taylor series of f(x) at x=0
compute the coefficients of x^4 and x^6 in the Taylor series of g(x) at x=0
f(x)
compute lim ------
x→0 g(x)
我知道泰勒展開式 可是我覺得這函數微一次就很醜了
還要微到四次六次九次 感覺就不是這樣算 請強者解惑 感恩
