Plotting Complex Variables on Argand Diagrams

Hello again guys,

I have the following problem:

Problem:

a) Plot the following complex variables on an Argand diagram

(i) 2 + j5

(ii) 3 - j6

(iii) - 4 + j10

(iv) - 6 - j3

b) Convert the (i) and (ii) above into their Polar Equivalents, show ALL working.

c) Add (i) and (ii) above and express the result in rectangular form.

d) Subtract (iii) from (ii) above and express the result in rectangular form.

e) Multiply (i) and (iii) above by first converting to Polar form and express the result in Polar form.

f) Divide (iii) by (iv) above by first converting to Polar form and express the result in Polar form.

IT'S PRETTY HARD I KNOW! can anbody help as i'm totally lost.
