There's a 'to the power x' too -.-

oh yeah... guess i miss typed it . i just drew a graph for y=x+3 seeking help from the previous reply to get the answer

Doing Maths after Add Maths seems like I'm doing Kindergarten in Grade 11. Such a Huge change in difficulty level.
For the first time and for surely the LAST, Thank You CIE!

MustafaMotani bhai meray thora halka haath rakho itni working aik post mein karo gay tu kiski samajh aayegi

LOL

 

[MustafaMotani]

hahahaha // isy waja say tu yeh DP hai .. warna tu kabki change kardi hoti

btw thanks for the center of rotation I didn't knew! actually which book has that chapter of transformations ? I couldn't find it in any of them ...

its in D4 appendix

 

[MustafaMotani]

To be frank, i didnt understand the method u used..

Soor I misunderstood the question ... I had to go at that time so I didnt read ur that post ..
SO have u got now. ??

 

[MustafaMotani]

aise sawal ai to i ll go blank in the paperssssss!!!

then prac alot for such questions...

 

[MustafaMotani]

Sarah22 we had to find distance of AB from top

I thought we had to find AB

IT would be 9 - 9cos 70 = 5.92
am I rite now.. ??

 

[MustafaMotani]

Help plzzz.... I'm doing this question on graphs . The graph is of the equation y=8(0.6)^x. The part i cant solve is find the solution of the equation 8(0.60)^x=x
how on earth can u solve that??? syed1995 ,@ashiqbal ,Dukeofwin MustafaMotani ... anyone??

SorrY i didnt respond I was not here

 

[MustafaMotani]

u should know the properties of circle very well, if D and E are tangents to the circle then it is obvious that CD = CE
and DC = 5 cm so EC becomes 5 as well.
the property is that two tangents coming from a single point outside the circle will be equal, here two tangents were coming from C so CE and CD are equal

Sin CAD = 5/13
so CAD = 22.6

 

[MustafaMotani]

is it necessary to memorize all those transformation matrices ?? is there no concept involved :\

yeah it is necessary
but wat do I do is write matrx x object's cordinate = image cordinate

I write matrix in the form of a,b,c,d and then after multiplication compare the values of a,b,c,d.
I know its quite time wasting but it comes quite handy when yu become blank during transformation.
THis method is also most accurate..

yar tum logo independent term kia arahi thi add maths p2 mein.. ??

 

[Translucent231]

[Spidey21]
