# Could you possibly find the inverse ?

**Algebra**Level 2

Andrew is currently preparing for a competitive exam but he is stuck on a probem related to inverse functions. He consults his friend who is pretty good at solving mathematical problems but he isn't able to solve it as well. Could you ?

If f(x) = x + Sin x and g is the inverse of f, then the value of g'( (5π / 6) + 1/2 ) is
