Expression of type ExprTuple

from the theory of proveit.trigonometry

proveit.defaults.automation = False # This will speed things up.

# build up the expression from sub-expressions

# check that the built expression is the same as the stored expression
assert expr == stored_expr
assert expr._style_id == stored_expr._style_id
