Why are the solutions different?
I am comparing the answers of the same equation between HP Prime G2 and HP27S.
I am entering a formula for distance between points using: " //MATH //COS A = SIN LT1 SIN LT2 + COS LT1 COS LT2 COS(LG1-LG2) //DISTANCE=C*ACOS(SIN(HRS(LT1))*SIN(HRS(LT2))+ // COS(HRS(LT1))*COS(HRS(LT2)) *(HRS(LG1)-HRS(LG2))) // 1 DEGREE OF ARC = 60 NAUTICAL MILES = PI X D/360 STATUTE MILES // WHERE D IS THE DIAMETER OF THE EARTH, 7917.59 //DEGREES.MINUTESSECOND FORMAT(D.MM.SSss) //EAST LONGITURDE ARE NEGATIVE NUMBERS. THE CALCULATOR MUST BE IN DEGREE MODE. // WHERE C IS CONSTANT: // C= 60 TO COMPUTE NATICAL MILES. // C=69.0940 TO COMPUTE STATUTE MILES. "N.B. When I enter the equation below into the Solver I get the answer:2,434.2929Statute Miles. The same answer if I ented the for PPL program. HMS-> entry goes to decimal form. D=69.094*ACOS(SIN(HMS→(40.35))*SIN(HMS→(44.35))+COS(HMS→(40.35))*COS(HMS→(44.35))*COS((HMS→(75.1)-HMS→(123.16))))" However, when I use My HP27s I get 2,426.9794 Statute Miles. This is correct for the formula backed up by my HP27s text. This discrepancy or difference in the answer is quite distressing. "wish PPL was QB/QuickC which one could program in a language of their choice...just trying to learn this program It's me I have to adapt. If anyone can figure this out please help is required....could it be the calculator... PS I am in degree mode. Thank You for your help, your attention to this matter would be greatly appreciated. |
