Testing inequalities in sage
I wanted to show if: $$ |a+b| \leq |a| + |b|$$
So I wrote this in sage:
var('a','b') eqn1=abs(a+b) eqn2=abs(a)+abs(b) bool(eqn1<=eqn2)
The result is False.
I had expected the result to be True. What is the correct way to test this in sage?
Thank you in advance for any help provided.
