Why is |x|/|x-1/x| so slow compared to |x/(x-1/x)|?

1

**Describe the bug** When using the graphing mode, |x|/|x-1/x| is noticeably slower (sub 1FPS on my machine) than |x/(x-1/x)|. **Steps To Reproduce** 1. Go to graphing mode 2. input |x|/|x-1/x|...

Request to add a method for rationalize like `rationalize(x::Quantity) = rationalize(ustrip(x))*unit(x)` since it returns an error otherwise

It would be nice if there where a convenient way to make a Polynomial without having to write out every time "Polynomial" For instance, including something like: ``` macro P_str(s)...

sincos leads to stackoverflow

Because of this bit of code ```julia _sincos(x::AbstractFloat) = sincos(x) _sincos(x) = (sin(x), cos(x)) sincos(x) = _sincos(float(x)) ``` in `julia\base\special\trig.jl` Calling sincos with a MultiFloat causes a stackoverflow. Minimum working...
