The limit of SiNx / (x ^ 2 + x) and SiNx / (x ^ 2 + X + 1) at 0 SiNx / (x ^ 2 + x) and The limit of SiNx / (x ^ 2 + X + 1) at 0

The limit of SiNx / (x ^ 2 + x) and SiNx / (x ^ 2 + X + 1) at 0 SiNx / (x ^ 2 + x) and The limit of SiNx / (x ^ 2 + X + 1) at 0

sinx/(x^2+x)
=sinx/[x(x+1)]
Because X - > 0, SiNx / x = 1, the above formula is
1/(x+1)=1
X - > 0, the numerator is 0 and the denominator is 1, so the limit is 0
