Tristan Thomas🤑 :
Just cancel out x and this thing turns into sindx which is just cos (but without x because it ran away)

Just prove it has no elementary antiderivative by showing its differential Galois group is non solvable 💔

$$ \sin(x) = \sum_{n=0}^{\infty} \frac{(-1)^n x^{2n+1}}{(2n+1)!} = x - \frac{x^3}{3!} + \frac{x^5}{5!} - \frac{x^7}{7!} + \dots $$ $$ \frac{\sin(x)}{x} = \frac{1}{x} \sum_{n=0}^{\infty} \frac{(-1)^n x^{2n+1}}{(2n+1)!} = \sum_{n=0}^{\infty} \frac{(-1)^n x^{2n}}{(2n+1)!} = 1 - \frac{x^2}{3!} + \frac{x^4}{5!} - \frac{x^6}{7!} + \dots $$ $$ \int \frac{\sin(x)}{x} \, dx = \int \left( \sum_{n=0}^{\infty} \frac{(-1)^n x^{2n}}{(2n+1)!} \right) \, dx $$ $$ \int \frac{\sin(x)}{x} \, dx = \sum_{n=0}^{\infty} \left( \int \frac{(-1)^n x^{2n}}{(2n+1)!} \, dx \right) $$ $$ \int \frac{\sin(x)}{x} \, dx = \sum_{n=0}^{\infty} \frac{(-1)^n x^{2n+1}}{(2n+1) \cdot (2n+1)!} + C $$ $$ \int \frac{\sin(x)}{x} \, dx = x - \frac{x^3}{3 \cdot 3!} + \frac{x^5}{5 \cdot 5!} - \frac{x^7}{7 \cdot 7!} + \dots + C $$ $$ \int \frac{\sin(x)}{x} \, dx = \text{Si}(x) + C $$

Cancel the x and integrate sin to get -cos duh 🙄

@agilobat :
x cancel out so the answer is integral

no elementary antiderivative but if it’s from 0 to infinity, u can use feynmans and get pi/2
