 Trigonometry Calculations 
  Before using the trigonometric functions (except hyperbolic calculations), select the appropriate angle unit 
(Deg/Rad/Gra) by pressing              .

  “Quotient” (Q) is the result in a division problem, “Remainde\
r” (r) is the value remaining in an integer division problem.
  The calculated quotient value (Q) and remainder (r) will be  stored into memory variables “C” and “D”, automatically 
assigned.
  In Maths mode, press      or      to scroll through a  long  calculation result.
  In Line mode, the quotient value (Q) and remainder (r) will be  shown over 2 lines.
  Only the Quotient Value (Q) can continue to be used for the  next calculation...
