Maths, Addmaths and Statistics: Post your doubts here!

[multixamza01]

do you have any quick revision guide like this for add maths? If so please post it...it will be very useful to all of us...also any other subjects like physics,etc

Add Maths Notes have been added. For Physics check the other thread on science subjects. I can't post it here as it would go against the topic.

thanks really appreciate ....but what i really wanted was the relative velocity part anyways its very useful and your doing a great job...THANKS

Hope you get this in time.

thnx they were gr8 notes but stil don't solve my problem bcuz they don't have number sequences and patterns in them... :/

number sequence and patterns are really easy

too bad then ..its probably your wild imagination or exams having wrecked u or poor eyesight... not deja vu definitely

where did u get the paper from... can u upload it so i can have a look ..im sure its out of syllabus now my teachers told me..confirmed

 

[daredevil]

number sequence and patterns are really easy

gud to hear that..... can u help me w/ it then? like is there any specific way to decipher the patterns (and i mean complicated patterns not the 1,3,5,7...)

Can somebody help me out in the transformation chapter? I'm having a bit of difficulty in making matrices...

Add Maths .

y11 specimen paper.

6 . Given that a = 5i – 12j and that b = pi + j, find

(i) the unit vector in the direction of a, [2]
Solved.

(ii) the values of the constants p and q such that qa + b = 19i – 23j. [3]
Help !

Substitute the vectors for a and b which are given into the equation and solve it simultaneously.
q(5,-12)+(p,1)=(19,-23)
(5q,-12q)+(p+1)=(19,-23)
5q+p=19 this is eq 1
-12q+1=-23 this is eq 2
Therefore
q=-2
p=29
