Is there any news Taylor has had lately, Taylor s latest news

There's not much news, there aren't enough scandals about the goddess.

Taylor Swift and Karlie Kloss appeared in the March 2015 issue of Vogue magazine.

Taylor Swift (Taylor Swift) wax figure officially entered Madame Tussauds in London, England, the cheerleading girl in the MV of "Shake It Off" attracted passers-by to take photos, Taylor Swift and Jamie King wore black "girlfriend suits" to attend the party after the Grammys.

Taylor is a European and American star.

I'll help the landlord answer it

Solution: Definition of Taylor's Formula:

If f(x) has an nth derivative at x0, then there is any point x(δ>0) in a neighborhood of x0 (x0-δ, x0+δ), and the following equation is given:

f(x)=f(x0)+f'(x0)/1!*(x-x0)+f''(x0)/2!*(x-x0)^2+…+f(n) (x0)/n!(x-x0)^n+o((x-x0)^n)

f(n)(x) denotes the nth derivative of f(x), and f(n)(x0) denotes the value of f(n)(x) at x0.

For the special function e x, use the Taylor spread: e x 1+x+x 2 2!+x^3/3!

x^n/n!According to Taylor's formula, the arbitrary derivative of the function e x at x0 is the function itself e x, so the floor is looking for e t=1+t+t 2 2!+.

t^n/n!, there is nothing wrong with that.

But when we use Taylor's formula to find e x 2, the arbitrary derivative of the function e x 2 at x0 is different, not e x, so it is not right to do substitution and bring in, but should bring in the McLaughlin formula according to the definition formula to find the result, which is correct.

I hope it will help the landlord to return to the ruler o( o

By the way, a digression, I see the landlord's handwriting, very similar to my college class president, weakly ask a few orders, are you old Yu?
