Regarding the substitution operation in mclaughlin formula, I can't figure out why x2 can be directly substituted into the X power expansion of E in the operation of x2 expansion.
. The derivative of Taylor formula can actually be regarded as the derivative of f(t) according to t.
Therefore, according to the invariance of the first-order form, we can see that the derivative of x2 to X is the same as that of T to T, can you understand it?
