im not really sure how to do this one because I have forgotten most of the things about trig functions from last year, but here is the problem:(adsbygoogle = window.adsbygoogle || []).push({});

(im going to say Ħ=pi because I cant find the character for pi)

f(x)= tan((Ħx)/4) when |x|<1

x when |x| =>(greater than or equal to) 1

Im supposed to find the x values, if any, at which f is not continuous, and find which of the discontinuities are removable.

I havent had a lot of problems with my split function questions, I just dont know how to handle it when trig functions are involved, can anyone explain?

Thanks
