Thread: ABOUT CALCULATION - Biorhythms

HI EVERYONE,,

this is my function and i will state the problem at the bottom..

Code:

//calculate the physical cycle which has physical curve 23 days
double physicalCycle(Date& dob, Date& currentDate)
{
   double score;
   double distance = distanceFromDobAndCurrentDate(dob, currentDate);
   
   score = 100 * sin(360*(distance/23));
   return score;
//check - the answer should be 63.10879473
}

when i entered
dob: 1 1 1969
current date: 1 6 2004

the output of the physical cycle should be 63.10879473 but it is wrongly output which is -80.---

can someone tell me wat is the problem, is it the formula or..?

this is the website u can calculate the physical cycle http://www.orcapia.com/froggy/biorhy...&detl=1&save=1

i though tat sin is in the library..

yes the distance is 100% sure correct
