I want to show that $F(x)$ is also continuous on $[0,1]$.
**MY WORK**
Let $\epsilon> 0$ be given and $x\_0\in [0,1].$ Since f is continuous at $x\_0\in [0,1],$ then $\forall x\in [0,1]$ with $|x-x\_... | 2018/09/07 | [

] | If you substitute $x \mapsto 2014-x$, you get
$$ I = \int\_0^{2014} \frac{\sqrt{2014-x}}{\sqrt{x} + \sqrt{2014-x}} \, dx = \int\_{0}^{2014} \frac{\sqrt{x}}{\sqrt{x} + \sqrt{2014-x}} \, dx. $$
Hence
\begin{align}
1007 &= \frac{1}{2}\int\_0^{2014} dx = \frac{1}{2}\int\_0^{2014}\frac{\sqrt{2014-x}}{\sqrt{x} + \sqrt{2014-x... | Don't need to do that substitution again and again just apply this formula
$$\int\_a^bf(x)~dx=\int\_a^bf(a+b-x)~dx$$
$$I=\int\_{0}^{2014}{\frac{\sqrt{2014-x}}{\sqrt{x}+\sqrt{2014-x}}dx}$$
Apply the formula
$$\int\_a^bf(x)~dx=\int\_a^bf(a+b-x)~dx$$
$$ I=\int\_{0}^{2014}{\frac{\sqrt{2014-(2014+0-x)}}{\sqrt{2014+0-x... |
