 Returns the hyperbolic cosine of a number.

 numberThe number you want the hyperbolic cosine of.

 REMARKS
 
  		• The "number" is the angle in radians.
     
  		• If "number" is not numeric, then #VALUE! is returned.
     
  		• If your argument is in degrees, multiply it by PI()/180 to convert it to radians.

     EXAMPLES
     
     A
    1=COSH(4) = 27.308
    2=COSH(-0.5) = 1.128
    3=COSH(EXP(1)) = 7.610
    4=COSH(ACOSH(1)) = 1
    5=COSH("some text") = #VALUE!
