Just under 15 hours til exam....I hate this so much...too much error rubbish -.-
I LOVE ERRORS!
i love all the math parts. the physics parts... notsomuch
i understand error bars and how to get the error ithe gradient. what i dont know how to do is get the error in other things .. like for ex nov 08 q2.d .. and they dont even have the answer in the mark scheme what do i do ?
they do tell you how to do it in the markscheme..
e/m from your gradient - e/m from worst acceptable line gradient
personally i would've done this by calculating the percentage error of the gradient, which is equal to the % error in e/m, then multiplying it by whatever value i got for e/m.
