when is a shear factor -ve...????

 

[Maganius]

hey guys any tips for p1?

Are your concepts clear?

 

[Maganius]

when is a shear factor -ve...????

Negative?
Aren't there just two matrices for Shear?

 

[asadalam]

when is a shear factor -ve...????

When it moves on the opposite side of the invariant line i think....

 

[Abdul Hanan]

Negative?

matrices are 2 i know..
but when is the "shear factor" negative...?

 

[Abdul Hanan]

When it moves on the opposite side of the invariant line i think....

you mean the other side of invariant line ??

 

[peacce]

Are your concepts clear?

yup
bus can u tell me significant figures ruleS???

 

[asadalam]

you mean the other side of invariant line ??

Yes.

 

[asadalam]

Transformation is a really effed up topic....

 

[Maganius]

yup
bus can u tell me significant figures ruleS???

Do you have Maths D-1 book?
If yes, read Chapter 4 from it.

 

[Abdul Hanan]

Yes.

but i thought...... in shear , the base line stays same ..

In a cumulative freq graph if the class is 0<m<(greater or equal to sign)10 do we have to plot x axis on 10 or on 5(i.e 10/2) ?

i think we would take five....i saw it in a paper once......tht way..

i think us banday nahi kahin say ghalat parhi hai #misunderstanding
coz its the only thing contrasting with all the info sstated there.

so is an empty set proper subset of a normal set?
total subset is 2^n?
proper subsets=( 2^n)-1 or 2^(n-1) ?

No we have to take 10,i saw it in the classified and also the ER.

no, improper*
yes
= 2^n - 2 just remember this.

no i dun hv

 

[Maganius]

yes
= 2^n - 2 just remember this.

Lol, wth is this?
Never heard of this expression before.

Faizan Muhammmad
give him the link.

 

[princess Anu]

no, improper*
yes
= 2^n - 2 just remember this.

what is a proper set?
8 is a cube number ?

 

[princess Anu]

Is the answer: 13x^2-18x-1=0 ?

no,there are 2 values of x, we have to solve it further
