TryReadSineCosinePowers

 Method with 2 overloads

• TryReadSineCosinePowers​(AngouriMath.​Entity,​AngouriMath.​Entity@,​PeterO.​Numbers.​ERational@,​PeterO.​Numbers.​ERational@,​AngouriMath.​Entity@,​System.​Boolean@)

  Summary

  TryReadSineCosinePowers(AngouriMath.Entity,AngouriMath.Entity@,PeterO.Numbers.ERational@,PeterO.Numbers.ERational@,AngouriMath.Entity@),
  and whether a fractional power of a product was read as the product of the powers:
  true only up to a constant on each interval where the factors keep their signs.

  Summary

  Reads expr as a rational multiple of sin(u)^p cos(u)^q over
  one common argument, however the six trigonometric functions spell it.
  

  Remarks

  A tangent contributes (+1, -1), a secant (0, -1), a cosecant
  (-1, 0) and a cotangent (-1, +1), so a product of any of them over one
  argument is a pair of integers. Anything else in the product — a second argument, a
  non-integer power, a function of the variable that is not one of the six — makes the
  whole read fail, because a rule that guesses at the part it did not recognise answers
  a question it was not asked.
