[hassam]

wat cautions i must take regarding significant fig in ppr2

 

[Zohaib Sherazi]

Round only your final answer to 3 significant figures and do not use rounded answers within calculations. Use raw reading only.

 

[hassam]

u mean for example the result on calculator by raw reading even if it is too long

 

[Zohaib Sherazi]

Yes. Only round the final answer.

 

[UxaiR]

give example to explain please .!

 

[Hashim]

if you get a value for sin55=0.819152044
then do not round it to .82 unless this comes in the final answer and carry on
this value to the next step

 

[UxaiR]

[Hashim]
