Q. Express z1=83+8i z_{1}=-8 \sqrt{3}+8 i in polar form.\newlineExpress your answer in exact terms, using degrees, where your angle is between 0 0^{\circ} and 360 360^{\circ} , inclusive.\newlinez1= z_{1}=
  1. Identify Coordinates: Identify the rectangular coordinates of the complex number. The complex number z1=83+8iz_{1} = -8\sqrt{3} + 8i has rectangular coordinates (83,8)(-8\sqrt{3}, 8).
  2. Calculate Magnitude: Calculate the magnitude (rr) of the complex number.\newlineThe magnitude is found using the formula r=x2+y2r = \sqrt{x^2 + y^2}, where xx and yy are the real and imaginary parts, respectively.\newliner=(83)2+82r = \sqrt{(-8\sqrt{3})^2 + 8^2}\newliner=643+64r = \sqrt{64\cdot3 + 64}\newliner=192+64r = \sqrt{192 + 64}\newliner=256r = \sqrt{256}\newliner=16r = 16
  3. Find Argument in Radians: Calculate the argument θ\theta of the complex number in radians.\newlineThe argument is found using the formula θ=atan2(y,x)\theta = \text{atan2}(y, x).\newlineθ=atan2(8,83)\theta = \text{atan2}(8, -8\sqrt{3})\newlineSince the complex number is in the second quadrant (negative real part, positive imaginary part), the angle θ\theta will be between 9090^\circ and 180180^\circ.
  4. Convert to Degrees: Convert the argument to degrees.\newlineTo convert radians to degrees, we use the formula degrees=radians×(180π)\text{degrees} = \text{radians} \times \left(\frac{180}{\pi}\right).\newlineHowever, we can directly calculate the angle in degrees using the atan2\text{atan2} function and considering the quadrant.\newlineθ=atan2(8,83)=135°\theta = \text{atan2}(8, -8\sqrt{3}) = 135° (since it is in the second quadrant)
  5. Express in Polar Form: Express the complex number in polar form.\newlineThe polar form of a complex number is z=r(cos(θ)+isin(θ))z = r(\cos(\theta) + i\sin(\theta)), where rr is the magnitude and θ\theta is the argument.\newlineUsing the magnitude and argument calculated, the polar form is:\newlinez1=16(cos(135°)+isin(135°))z_{1} = 16(\cos(135°) + i\sin(135°))
