Any list of rules of log applicable in the Paper 5 ?

You are welcome.Thanks so much!
i know to draw best fit but have no idea about worst fit line...so guys plzz help me on this..!!
thank u sooooo much..!! Allah bless u..hi
The worst fit line is the line u draw after drawing the error bars
draw the line from the highest error bar of the first point to the lowest error bar of the final point
how it helped
can any1 guide me how to calculate absolute errors in gradient and y intercept? alsoow to how to draw worst fit line in graph? plzz
error in gradient= gradient of best fit line - gradient of worst acceptable line
error in y-intercept= y-intercept of best fit line - y-intercept of worst acceptable line
for drawing worst acceptable line check out the previous post u just have to draw the line from highest error bar of first point to lowest error bar of last point
The syllabus states recognize and use the logarithmic forms of expressions like ab, a/b, x^n, e^kx and understandAny list of rules of log applicable in the Paper 5 ?
Ramsha007 tel me how to do quest 2 part c in http://papers.xtremepapers.com/CIE/...and AS Level/Physics (9702)/9702_s09_qp_5.pdf
The third step is only done if the answer of error in (gradient= gradient of best fit line - gradient of worst acceptable line) is negative so u can decide which one to use on the bases of seeing which value is bigger because u need a positiveerror value
- calculate the gradient of best fit line
- calculate the gradient of worst fit line
- error=worst gradient-best gradient (BECAUSE OTHERWISE THE CHANGE IS NEGATIVE)
Hope this helps
,....Error can both be either positive or negative..so it does not matter whether u get positive or negative error because gradient(+_)error...The third step is only done if the answer of error in (gradient= gradient of best fit line - gradient of worst acceptable line) is negative so u can decide which one to use on the bases of seeing which value is bigger because u need a positive error value

U are correct although it is said to calculate the gradient error this way in the marking scheme to get positive answer.May be the examiner recommends this or something,....Error can both be either positive or negative..so it does not matter whether u get positive or negative error because gradient(+_)error...
So u do the other way round and the negative sign goes away.U getting negative answer from best gradient-worst gradient in this question
Read my comment #9can anyone plz help me informing how to draw error bars and then join them?for example in o/n2011 varient 51, Q2 .
