The discussion revolves around converting the complex number -3 - 5i into polar form. Participants are examining the calculations related to the modulus and argument of the complex number, as well as the correct representation in polar and exponential forms.
There is an ongoing examination of the calculations presented, with some participants suggesting corrections to the angle and questioning the use of different forms of complex numbers. Clarifications are being sought regarding the calculations and assumptions made in the original post.
Participants note the importance of using radians for the calculations due to the integer nature of the components of the complex number. There is also mention of potential confusion regarding the tangent values used in the angle calculations.
tan Q = 5/3, but 5/3 is not equal to -1.12r-soy said:write in polar form ...elc
-3 - 5i
my answer :
x = -3 y = - 5
r = root (-3)^2 + (-5)^2
= 5.83
tan Q = 5/3 = -1.12
r-soy said:tan-1 -1.12 = -0.84
Q = -0.84
Q = -pi + -0.84 = -3.981
Polar form = 5.83e^(-3.981)i
