How do we evaluate this limit without the use of L’hospital’s rule?

lim
x -> 0 (tan-1 x)/x

I know that it’s 1 using L’hospital’s rule or numerically but what about alegbraically? Thanks in advance and really appreciate it. I don’t know how to use Latex or anything like that sorry that the limit is horribly written, and it’s my first time here.
