limsin(x^2)ln(x) = lim{ sin(x^2) / x^2 * x^2 * ln(x) } = lim (sin(x^2) / x^2) * lim(x^2 * ln(x)) = 1 * lim(x^2 * ln(x)) = lim(x) * lim(x * ln(x)) = 0 * lim ((1/x) / (1/x^2)) = 0 (洛比达法则).
limsin(x^2)ln(x) x趋向于0且从正方向
limsin(x^2)ln(x) = lim{ sin(x^2) / x^2 * x^2 * ln(x) } = lim (sin(x^2) / x^2) * lim(x^2 * ln(x)) = 1 * lim(x^2 * ln(x)) = lim(x) * lim(x * ln(x)) = 0 * lim ((1/x) / (1/x^2)) = 0 (洛比达法则).
