its not allowed but people do take it and use it without any one knowing abt it !

can u solve So9 Qp_2 Q4 rotational symmetry question of mathematics 4024

 

[scouserlfc]

can u solve So9 Qp_2 Q4 rotational symmetry question of mathematics 4024

the part for rotational symmetry that is 4)a)i)a is order 3 try using the centre of the shape as the invariant point and rotate it, (one trick of doing it think about it as a stencil u have of this shape and u take the shape out and rotate it and fix it u will see u can do it 3 times !

hey guys...if your having problem with differentiation here is a link with alot of videos....related to maths and add maths..:lol:

look, there are two kinds of patterns
one which have same increase all over like
1 , 3 , 5 , 7 etc now the difference here is 2...

the other type of pattern is

1, 5 ,13 , 25 ,etc over here the difference is increasing by four every time...so the increase in the difference or the difference of the difference is the 2nd difference...samajh aya??? i thought alot on it..if you still dont get it i will try to rephrase it....

yea thank u so much....i get it so c is the difference of the difference ryt?

 

[Vogue]

wat is rotational order of symmetry and how do v know that how many lines of symmetry can the figure b divided into?

 

[Spidey21]

yea thank u so much....i get it so c is the difference of the difference ryt?

yes exactly , it is the difference of the difference...

 

[Spidey21]

wat is rotational order of symmetry and how do v know that how many lines of symmetry can the figure b divided into?

rotational symmetry can be seen by rotating the figure, the thing is that the number of times it maps onto the original figure while in a complete rotation of 360, that is the number of rotational symmetry and you have to make lines of symmetry that equally divide the figure into two figures and then you will know how many you have....for example take in mind a square...

a square has 4 lines of symmetry and has 4 rotational symmetry...

For line of symmetry...Really fun and cool and interactive practice

[kitecrystal]

can anyone plz explain Q15 part (c) of this paper??

oh spidey Thank u so much!

 

[Spidey21]

oh spidey Thank u so much!

no problem....its your Neighbourhood Friendly Spider Man..
Lol what did i write that for???
LOL

 

[Spidey21]

now whats the difference between and except for colour???

 

[Spidey21]

can anyone plz explain Q15 part (c) of this paper??

could you please share whats the actual answer on the marking scheme?

 

[Spidey21]

can anyone plz explain Q15 part (c) of this paper??

i guess it would 2 minutes and 45 seconds....part c, the range...

 

[kitecrystal]

could you please share whats the actual answer on the marking scheme?

its 2 45
