[Aizen]

can anybody tell me the center of rotation in transformation .!

(0,0)

 

[sjs]

the centre was the origin

 

[sunshine]

mine center of rotation was (2,0) any chances to get marks?

 

[Aizen]

i dun think so.

 

[sjs]

umm..if u wrote that it was 90 degrees anticlockwise ...u'll get half the marks

 

[Aizen]

yes that may b da case

 

[sunshine]

i wrote 90` anticlockwise from center of rotation (2,0)

 

[sjs]

u'lll get a mark for that then

 

[M.Usman Khan]

yup i think it was a two mark qs

 

[Aizen]

i wrote 90` anticlockwise from center of rotation (2,0)

by the way how come u thought of the centre 2,0

 

[sunshine]

by making 2 bisects and joining them
maybe wrong in using instruments =(

 

[sjs]

hmm..
and that circle question...the angles were
52
52
38
correct?

 

[Aizen]

yep

 

[UxaiR]

and that circle question...the angles were
52
52
38
correct?

i got the same .!

umm...if u wud've used the matrices...u wud've identifies that the centre was the origin...

identified*

 

[Aizen]

matrix method is safer

 

[M.Usman Khan]

marices only used when confirmed that center is origin...

the angle values r confirmed correct.

 

[M.Usman Khan]

sure is...

 

[momen]

okay guys can anyone tell me that how many marks were of that string question B part .!


and this is what i did do you think i will get marks


50-5 = 45

395 - 45 = 350


plz any marks for this ??
