| [[antiderivative]] || the [[sine integral]] (''this is defined as the antiderivative of the sinc function that takes the value 0 at 0'')

| [[power series]] and [[Taylor series]] || The power series about 0 (which is also the Taylor series) is<br>$\sum_{k=0}^\infty \frac{(-1)^kx^{2k}}{(2k + 1)!} = 1 - \frac{x^2}{3!} + \frac{x^4}{5!} - \dots$<br>The power series converges globally to the function.
