Some trigonometric expressions can easily and quickly be simplified without ever calculating some of the functions in it just by using the known properties of the functions in the expression.
For example: sin(2*pi) is 0. So: sin(pi*factorial(847937526693730893984732849857349)) is also 0. This does not require calculation of the factorial, but the property knowledge, that the result of the factorial is an even integer. There are several other examples of expressions, like: tan(pi*(1342^(87236487262873^(8732498237693269832+3)+5)-1)) is also 0. Several others: cos(pi*(factorial(8629264243264^64862423642638763847)+1/2)) is 0. Could this be implemented in sympy? So many other examples would be much faster to calculate. -- You received this message because you are subscribed to the Google Groups "sympy" group.
