RE: Findroot

Try  ?? solve

for example         solve(x=1,2,cos(x))

or                          solve(x=-1,1,x-cos(x))

You can use \p100 to get 100 digits.

Is there a function in PARI library which is equivalent to Findroot in Mathematica?

For example:

FindRoot[Cos[x] == x, {x, 0}] 

will find a solution to cos(x)=x near x=0  

Thank you in advance,
