Best ResponseYou've already chosen the best response.0I meant \[5 \sqrt{3} 5i\] How do I plot the sqrt 3?

Best ResponseYou've already chosen the best response.1so, 5(root)3 would be your x coordinate then 5i would be your y

Best ResponseYou've already chosen the best response.1I guess you just have to work out roughly where 5(root)3 would be on your x axis

Best ResponseYou've already chosen the best response.1Yeah, 5i is on the y axis, however, the Y acis on an argand diagram is actually in terms of i

Best ResponseYou've already chosen the best response.1You can use the fact that there is a 306090 triangle involved. This means you can find the point exactly. Sound a bit complicated, so I'll try to make a drawing... (just hold on a sec!)

Best ResponseYou've already chosen the best response.1You can recognise it by the combination of numbers, e.g. 2+2√3 i, or 5√35i...

Best ResponseYou've already chosen the best response.0How would I plot 2 + i ? Would it make the 2 on the y axis also?
