Its in the addendum of D3 maths,or if you have a more recent book it'll be there at the end.

Did another P1 slowly improving,1st one was 76 and 4th one is 78

Are you sure it's D3? Meri D3 main koi addendum nahi hai. :/

 

[FLRNAB]

no.
from 6-8 its a curve with decreasing gradient, and from 12-20, its a curve with increasing gradient,.

Yeah but Rxaminer Eport.

D4 main mil gya hai.

see ms.
screw what examiner report says if u are right.
by appreciated er means, that curve graphs were not regarded as better than those which were straight, coz they were v rare.

amd is right,complemented by ER;ER says tht "it was not appreciated tht acceleration means a curve" or sth like tht.So it means tht we have to consider the acceleration factor in speed time graphs and a curve WUD be produced.Not appreciated means tht many did not consider the factor of acceleration and went to produce those straight lines instead

So they accepted the straight line graphs too?

Good now?

a curve b/w 8 and 10 too!

Oh sorry wrong reference to amd..wht I meant was tht he was right in telling u tht graphs had to be a curve at those stages...And tht straight line graps wud of course not score full marks...Again ,unappreciated means tht the students did not consider the acceleration factor in speed time graphs and did not draw the curve for tht acceleration on distance time graphs
decr gradient curve bt2 6 and 8 as well

 

[Asad.Babur]

what can i say.....its the evident truth...........

The box is too small to show the curve.

a curve b/w 8 and 10 too!

Const speed there.

Madam, it must be (4, 4) check it!

Sir , it's 6,2 . That is why I don't get it!

how to find angle of rotation
:/?

 

[FLRNAB]

how to find angle of rotation
:/?

1) Take 2 corresponding points and join them to the center of rotation.
2) Find the angle between the two lines in respect of the direction of rotation.

use a protector for that :3

 

[FLRNAB]

Damn.

 

[exploded diper]

How to find center of rotation?

didnt expect tht from u.....

 

[exploded diper]

but the ms says 1/13

 

[exploded diper]

Yeah but Rxaminer Eport.

where do u find the Rxaminr report...every time i check it gives me thsi Examiner report..........
