When x tends to 0, (1 + SiNx) ^ (1 / 3) - 1 is equivalent to
When x tends to 0, SiNx tends to 0, so (1 + SiNx) ^ (1 / 3) - 1 = 0
Why is SiNx / X equal to 1 when x tends to 0
Is the limit equal to one
The denominator of the limit molecule can be derived at the same time according to the law of Robida
lim（x→0）sinx／x=lim（x→0）(sinx)'／x'=lim（x→0）cosx=1
