How to convert a Taylor series into a formula?

Question

Programming

1 + x/2 + 3*x^2/8 + 35x^4/128 + 63x^5/256 + 231x^6/1024 + 429x^7/2048 i td
can't make a formula out of this to implement on c++.

Answer 1

And this is probably not a Taylor series for you :)
Because in the Taylor formula, the denominator is n!, And in your formula 2 ^ n - the denominator grows much more slowly.
Taylor series:
Consider a=0.
And try to find the values ​​of the derivatives for each member of the Taylor series.
Next, make a table, maybe it will help you find the right formula expressing the value of the derivative of n.
At least f'''(0) = 0 for you.

Answer 2

Have you even tried? If yes, please show the code. If not, then take it and try it. It's very simple
