Plz see if this argand diagram is correct...and ignore the quality of linesView attachment 64634
Yeah there will be multiple answers for 9(ii)
Why are you giving composite I remember you had an A in maths in As. Or I guess I am wrong?Composite
Yes I had an A but I wasn't satisfied with itWhy are you giving composite I remember you had an A in maths in As. Or I guess I am wrong?
What do you mean NOT satisfied?Yes I had an A but I wasn't satisfied with it
I got the same diagramPlz see if this argand diagram is correct...and ignore the quality of lines
I could see the A* at risk that's whyWhat do you mean NOT satisfied?
come on why make your study routine so hectic?
Do u have notes of geometrical effects of multiplication and division of complex numbers?I got the same diagram
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 diagramDo u have notes of geometrical effects of multiplication and division of complex numbers?
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.Anyone part 3 with solution?
Alright and will division do the reverse? And what if it is multiplied by a complex number?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
