can u simplify it more into indices form...

2 x 2^1/2 x 2^1/4

 

[exploded diper]

2 x 2^1/2 x 2^1/4

so that would make it 2 ^ 7/4

 

[exploded diper]

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

how to make em by oneself

 

[TheValiantGuardian]

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

:/

View attachment 43807 it will be 90 degree anti clockwise

How do you know it's 90 anticlockwise, they didn't mention.

how to make em by oneself

Plot a graph sketch with points on identity matrix (1,0)(0,1)
Rotate them and see new points and then make the matrix.

Yar wht abt when we have to draw a v/t graph based on d/t graph...The prob here is the sudden shift if d/t graph as it goes from having a gradient to 0 gradient.In the v/t graph this means tht the speed suddenly plummets.Does this mean we have to break the graph of v/t at tht point when the gradient suddenly becomes 0 and wud start it from zero:There shud be no trailing line?

so that would make it 2 ^ 7/4

Bingo!

What's the answer?

Yes because the d/t graph shows speed is zero and we have to show that in v/t graph. Bro you can't teleport in graphs.

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) ?

In a cumulative frequency graph, classes are like <10.. and stuff... and the frequency is against that.
So you plot 10 against it.

Q8a

Sin x = (Sin 180 - x)

So, 180 - 32 = 148.

 

[mohammad ahmed]

Sin x = (Sin 180 - x)

So, 180 - 32 = 148.

thanks!!!
gud luck everyone

 

[M.Omar]

Yes because the d/t graph shows speed is zero and we have to show that in v/t graph. Bro you can't teleport in graphs.

Ok then

 

[FLRNAB]

Sin x = (Sin 180 - x)

So, 180 - 32 = 148.

Explain please.

 

[Dark Destination]

Explain please.

 

[M.Omar]

Explain please.

And abt those estimation question queries of mine?Maths, Addmaths and Statistics: Post your doubts here!

It,s pretty understandable ..this concept, not like tht we blindly memorise the law or anything
