Yeah you did, I knew how they got x+y=5 I was talking about how you identifed the other two ineuqlaities from the graph.

Well I looked for the lines the question didnt gave ofc... Am I not clear? Plz let me know...

 

[zainabkhann]

No you are. But I meant the answer that you got from that answer. I'm asking what steps did you go through in ur brain to determine that. Like how did you go through the graph and figured the last 2 inequalities ?

Well I looked at the lines around the shaded part. Then I looked at the equations of the lines the questions didnt gave. I cant really seem to understand ur question...

Can someone please help me with this trig question.
In the shape shown, determine the size of angle KLM.
I found the side of the green triangle to be 80, but then couldnt solve after.

Thanks !

And can someone also explain to me what formula should be used when in trig I always forget which one to use for example: sine, cosine rule etc.

Can i get notes on differentiation,Rate of change ,higher derivatives &application...
Also with the formula for Volume, Area,Perimeter Surface area of various shapes..!

I also need Old Past papers before 2002 of Math and Add.Math.

I also need Old Past papers before 2002 of Math and Add.Math.

For that u wont get any of them online,so u should buy the classified Past papers of Add maths and Maths they have answers of those questions as well so no worries but definitely u will have to buy them

 

[zainabkhann]

Is the answer 12.3?

Yeah thanks for this!

 

[zainabkhann]

Yeah it is thanks!

can you give me pointers on vectors in two dimensions, I need some notes, to help me understand that chapter, so I can solve the past papers.
