i don't know how to put these equations into perfect squares so i can get the complex number to put on the Argand diagram
(^ means 'to the power of' because i don't know how to use small letters)
and theres something else in the text book that doesnt make sense to me.
Determine the values of x and y by equating real and imaginary parts
can someone please try to solve these step by step so i know how you did them.... thanks!
