Python Q.nonnegative Examples

Example #1

File: order.py Project: A-turing-machine/sympy

 def acos(expr, assumptions):
     x = expr.args[0]
     if ask(Q.nonpositive(x - 1) & Q.nonnegative(x + 1), assumptions):
         return True

Example #2

 def acos(expr, assumptions):
     x = expr.args[0]
     if ask(Q.nonpositive(x - 1) & Q.nonnegative(x + 1), assumptions):
         return True

Example #3

File: order.py Project: A-turing-machine/sympy

 def asin(expr, assumptions):
     x = expr.args[0]
     if ask(Q.positive(x) & Q.nonpositive(x - 1), assumptions):
         return True
     if ask(Q.negative(x) & Q.nonnegative(x + 1), assumptions):
         return False

Example #4

 def asin(expr, assumptions):
     x = expr.args[0]
     if ask(Q.positive(x) & Q.nonpositive(x - 1), assumptions):
         return True
     if ask(Q.negative(x) & Q.nonnegative(x + 1), assumptions):
