can somebody tell me how many decimals places for this question and tell me if i am doing this right
1. Calculate a value for the expression
p=a^-2
a=27.3 +- 0.05 metres ( the plus and minus symbol is on top of each other)
b) calculate the maximum error in your answer
this is what i did
for a) p=27.3^-2 = 0.001342 is that how many decimals i put down how many do i put down
b) to calculate the maximum error i differintiated the questio so i got -2*a^(-3) therefore
-2(27.3)^(-3) * 0.05 = 4.91 * 10^(-6)
is that how i put the form in how many decimal places?
do i state the maximum error is 4.91*10^(-6)?
ok if somebody can answe those questions thanks!
