suppose if I = 1.2
the value la log(i) should be in how many figures???? in 2 or 3???????

 

[CaptainDanger]

I guess 2...

always use 3 sf!
its more reliable!

 

[Fauziya]

so its 0.079...

advise:
if ur asking for phy p5, then they have a graph with a labelled and given axis. so for that look at the divisions and
for ex: there are 10 divisions between 2.46 ......... 2.47.
then acc to that, each division is 0.001.. its like 2.461, 2.462... and so on.
so ur readings are supposed to be 4 sf. then it will give u a more accurate graph... if u take 3 sf (u round off...) that will give u a VERY different graph. with very random points...
BUT! if ur not doing p5 for phy. then this is not required at all, take 3 sf. ull have a great graph
best of luck!!

It depends on the Question.if the Q has 2 or 3 sig fig then use 2 or 3 but if you cant figure out keh question mein kitne sif figs hain tou always go with 3!

 

[marlpi29]

so it means that..if the digit to be logged had 2 s.f. then, the ans should be written i 3 s.f?? it it was 3 then 4 sf?

 

[princesszahra]

always 3!
