From this code :

Declare symbols :

from sympy import *
r,l,c=symbols('r,l,c', real=True)

The first equation :

b=sqrt(2)*sqrt((-r**2/l + 2/c)/l)/2
display(b.simplify())
display(b.subs({r:1,l:2,c:3}))

Second equation :

d=sqrt(-c**2*r**2+2*c*l)/(sqrt(2)*c*l)
display(d.simplify())
display(d.subs({r:1,l:2,c:3}))

There are equals but not here :

display(simplify(b-d) == 0)

False

h=simplify(b-d)
display(simplify(h))

It cannot be simplified

I have 2 questions :

1. How cant I get equation in 2 lines (pretty print ) like the ‘d’ equation ?
2. How to retrieve equality ?

Thanks
