      Unfortunately, you cannot find the antiderivative of this function in terms of single-variable elementary functions. There is just no answer you can give using arithmetic operations, exponents or powers, trigonometric functions, hyperbolic functions, or the inverses or compositions of any of the above. Wolfram Alpha gives an answer that requires imaginary numbers and uses special elliptical integrals.

    • @dawsonbowhay6796
      @dawsonbowhay6796 4 года назад +2

      A Taylor series is infinite, but in practice we may only use the first few terms of the Taylor series as a close approximation to the true function. Therefore, all the [infinite] remaining terms that aren't used are equal to the error between the approximation and the true function. If you graph the true function and the approximation, you will see that there will be zero error at x=a, but as x gets further away from the value a, the error increases. You might choose a certain value of a based on which values of x you want your approximation to be accurate for. Or, you might have to use a non-zero value of a if the function is undefined at x=0 (take for example y = 1/x, where you can't divide by zero so a=1 would probably be used).

For what values of n are n - k and k + 1 co-prime (relatively prime, they share no common factors) for all k? In other words, for what values of n is gcd(n - k, k + 1) = 1 for all k satisfying the conditions I established?

      The operation which combines a/b and c/d to give (a+c)/(b+d) has the interesting property that it guarantees a new fraction which lies between the two source fractions and is very helpful in various proofs, the nature of which also escapes my memory right now.
