Q) Find a bijective function f : (−1, 1) → R. (Here (−1, 1) is the open interval (−1, 1) = {x ∈ R | − 1 < x < 1}.) I am struggling with this one. Could I just choose some heaviside step function?

Could I just choose some heaviside step function? The tangent function will work you will need to change its domain a bit. Good luck.
Thanks, I should not have sworn off trig functions so fast ha.
