Mathematics: Post your doubts here!

[Ebrahim12]

All of my answers match yours except 9 ii but for such type of questions multiple answers are given in the ms. Right?
And plz share the solution of Q5

Yeah there will be multiple answers for 9(ii)

Plz see if this argand diagram is correct...and ignore the quality of lines

Composite

Why are you giving composite I remember you had an A in maths in As. Or I guess I am wrong?

Yes I had an A but I wasn't satisfied with it

What do you mean NOT satisfied?
come on why make your study routine so hectic?

I could see the A* at risk that's why

Anyone part 3 with solution?

Hi
I was wondering where you could find February March 2019 papers for AS level, For bio chem phys and maths

Assuming you have OD from the second part

You can draw a right angle triangle between O, A and the midpoint of OD.
Like this:


Then the hypotenuses gives you the distance

Guyz i need advice for p3
I have done topical once of whole subject..I dont have much time now for p3 and i am also not good in p3 now should i do yearly or topical(like 10-20 question of each chap)?

can I get revision notes for math P1 and S1

I got the same diagram

Do u have notes of geometrical effects of multiplication and division of complex numbers?

 

[Legend_Liy]

Thanks alottt. You have been great help.

Hi Everyone. Just wanted to say that theres this website for Math which you may or may not know so Ill send the line below. It has amazing explanations for each question of every variant of years from 2002 to 2017 for Pure math 1 and 2.

No, I know that multiplying a number by i adds pi/2 to its argument and multiplying it by a real number multiplies its length in the argand diagram

Use trigonometry... draw a triangle AOD(with the perpendicular) and find the length of all sides. You have vectors AO, OD and can find AD. Find the magnitude of these vectors(they will be the lengths of the sides of the triangle). Now find an angle AOD or ADO and use the angle to find the perpendicular's distance using basic trig.
Check my diagram to understand this.

No, I know that multiplying a number by i adds pi/2 to its argument and multiplying it by a constant multiplies its length in the argand diagram

Alright and will division do the reverse? And what if it is multiplied by a complex number?
