agrument of z is the angle theta such that cos theta= x/z modulus and sin theta = y / z modulus. and it is only defined up to the addition of muliples of 2 pie.
can u exaplin this statement
"it is only defined up to the addition of muliples of 2 pie."
One last question.
express the following complex number in polar form
now r =1
cos inverse= 0/2=90 * pie/180= pie /2
sin inverse = 1/2= 30 *pie/180 =pie/6
now answer is e ^ (ipie / 2)
Question is why do we take theta value of pie/2 and not pie/6. i have done other questions as well. some time we take theta value which we get thrrough sin and some times the one we get through coz.WHY IS THAT ...PLZ HELP
