converts exponentials in expr to trigonometric functions.
  • ExpToTrig generates both circular and hyperbolic functions.
  • ExpToTrig tries when possible to give results that do not involve explicit complex numbers.
  • ExpToTrig automatically threads over lists, as well as equations, inequalities and logic functions.
