x→∞ lim (x+sinx)/x=?rt
x→∞ lim (x+sinx)/x
= x→∞ lim (1+sinx/x)/1
= x→∞ lim (1+sinx/x)
= (1+0)
= 1
x→∞ 则(x-1)/x≤x≤(x+1)/x
∵ x→∞ lim (x-1)/x=0
x→∞ lim (x+1)/x=0
∴ x→∞ lim (x+sinx)/x=1
x→∞ lim (x+sinx)/x=?rt
x→∞ lim (x+sinx)/x=?rt
lim(x→∞)(x-sinx)/x=?
lim(x→∞)[(x+sinx)/(x-sinx)]=?
lim x→0 x/sinx=
为什么lim x→∞ sinx/x =0而lim x→0 sinx/x =1?
lim (x→0)x-sinx/x
lim(x→∞)(3x+sinx)/(2x-sinx)的极限
x→∞ lim(3x+sinx)/(2x-sinx)=
lim(n→+∞)(x-sinx)/(x+sinx)问题是X趋于无穷大!不是趋于0
x→∞ lim(cosx+x)/(sinx-x) 求极限?
lim√x(sinx+cosx)/x+1 x→+∞
lim(x→∞) (xsin(1/x)+1/x(sinx))
lim(x->0) x/sinx=?lim(x->∞) x*sin1/x=?
求极限lim|x->∞ (x+sinx)/x=
lim(x→0)[e^x-e^(-x)]/sinx=?
当x→0时,lim (x-sinx)/x=?
lim(x→0)sinx/|x|rt
