lim(x→-∞)[(√(x+2)(x+5))+x]=__.
设lim(x→0)[f(x)-3]/x^2=100,求lim(x→0)f(x)
已知lim(x→0)[f(3x)/x]=3 求lim(x→0) [2x/f(5x)]
lim(x→∞)[(a x^2)/x+1]+bx=lim(x→∞)(a x^2)+bx(x+1) / x+1=lim(x
f(x)在正负无穷内可倒,且在x→∞时 limf '(x)=e,lim[ (x+c)/(x-c)]^x=lim[f(x)
已知f(x)是多项式,lim x→∞【f(x)-2x^3】/x^2=2 ,lim x→0【f(x)/x】=3 求f(x)
lim(x→∞)x(π/2-arctanx)
lim(e^x)cosx= x→+∞
求极限 lim x→∞(2sinx/x-)
极限lim x→+∞ [x-√(x²-1)]=?
求极限值,limx→(x^2-1/x-1)和lim x→∞(2x^3-3x^2+4/5x^3+x-7)谢谢!
lim(√(4x²-8x+5)+2x+1),x→-∞怎么解?
