Root 4 kaise aya
/52 tk ma na b kr liya tha age samaj nae aya

13 x 4=52
Square root of p into square root of q is square root of pq so we can create factors and divide it.

he divide 52 into 2 parts that makes 13 and 4. 13*4=52.

ok ok

 

[princess Anu]

why would you even multiply y with 4 and 5?

to make a common denominator ?

 

[funky brat]

to make a common denominator ?

you have 12 y as the denominator so to make that 3y 12, you just need to multiply it with 4 not 4y.

Can anybody please let me know is this correct? Thanks in advance.

Can anyone one construct the locus and post here? I always get 1.5 cm in the last part but the mark scheme says it's 2-2.5. What gives?

There is sometimes a difference due to the size of the drawing. Like on the original CIE paper the lines are slightly bigger than our normal A4 paper or the computer. So dont worry!

Do you print and do it?Make sure you print actual size...

 

[Muhammad_Hamza]

Yeh Matrix kaise nikalte han Transfornation ka???

Yes. Actual size. Maybe I'm constructing the locus wrong.
Is it like this?

 

[exploded diper]

it will be 90 degree anti clockwise

 

[Muhammad_Hamza]

View attachment 43807 it will be 90 degree anti clockwise

Yeh yaad krne han sare Matrix??

 

[ciesgetoveralready]

Can anybody please please please let me know this?

 

[asadalam]

Yes. Actual size. Maybe I'm constructing the locus wrong.
Is it like this?

Its slightly wrong,P is not on the line DC,its inside the shape...try making it again.

 

[kirann]

Yeh yaad krne han sare Matrix??

samjh lo khud he yaad hojaeingy... in short yaad he krne hein

 

[exploded diper]

Yeh yaad krne han sare Matrix??

yup

 

[kirann]

plz somebody explain part b

 

[asadalam]

yup

Its better to make them by yourselves,sometimes rattay mai mixup hojata hai...
