Part 2: How to expand trigonometry identities using the SymPy library with Python
Expand the trig identities using SymPy
#mathematics #python
Code:
from sympy import *
init_printing()
var("A:B")
(sin(A)**2 + cos(A)**2).equals(1)
expand_trig(sin(A+B))
expand_trig(sin(A-B))
expand_trig(cos(A+B))
expand_trig(cos(A-B))
expand_trig(tan(A-B))
expand_trig(tan(A+B))
(sec(A)**2).equals(1+ tan(A)**2)
(sin(2*A)).equals(2*sin(A)*cos(A))
