i can't understand how to solve this issue: using an appropriate substitution, evaluate this integral:
$$
\int \frac{1+x²}{\sqrt{1+x}}\mathrm{d}x
$$
can any one solve this so i can understand how to do this.


Question: Is Roy based on Quentin Tarantino and Sofia Coppola?
Answer: Yes. According to The Times of India it's based on/inspired by their affair.

Initially, they cited a source close to production who commented:


  Vikram (Vikram Singh, the director) is a fan of both the filmmakers
  and he wanted to create a narrative around the affair between the two
  movie greats.


They later confirmed this directly with Vikram Singh:


  When contacted, Vikram Singh confirmed the news, saying, "The
  Tarantino-Copolla affair has definitely inspired our plot. And I've
  had several discussions with my cast about the same. Both Jacky and
  Arjun have been reading up extensively about the two directors to get
  the nuances of their personalities right," he said.


Edit:

I suppose it depends on whether you consider inspired by to be as good as based on. The fact the director has confirmed the two leads have been reading up on the two directors' personalities is enough for me to stand by my claim. Even if they haven't followed Tarantino/Coppola to the letter, it certainly seems it was based on their doings (with some artistic license as well).
