Determine all values of the constant a such that the following function is continuous for all real numbers.(adsbygoogle = window.adsbygoogle || []).push({});

f(x) = ax/tan x, if x≥ 0

a^2 -2, if x<0

I've tried to plug in zero but the tan x throws me off because plugging in zero will give me a 0/0. Other than that I am stuck on what to do.
