lim(1/(sinx)^2-cosx*cox/x^2)=?x.0
举一反三
- lim(x→0)(sinx^2)/[(sinx)^2]求极限,x趋于0,
- lim(x趋向于0)(1-cosx^2)/((x^3)*sinx)
- 【单选题】5.设f 0 (x)=sinx,f 1 (x)=f 0 ′(x),f 2 (x)=f 1 ′(x),...,f n +1 (x)=f n ′(x),n∈N,则f 2011 (x)等于() A. sinx B. -sinx C. cosx D. -cosx
- lim(x->0)[1-x^2-e^(-x^2)]/[x(sinx)^3]
- lim(x/2)^(x/x-2).x趋向于2!第二题:lim(e^(x)-1/x).x趋向于0
