irina [24]

To divide complex numbers in polar form, divide the r parts and subtract the angle parts. Or


<span><span><span><span>r2​</span><span>(<span>cos<span>θ2​ </span>+ i</span> sin<span>θ2​</span>) / </span></span><span><span>r1​</span><span>(<span>cos<span>θ1 </span>+ i</span> sin<span>θ1​</span>)</span></span></span>​</span> <span>= <span><span><span>r2/​</span><span>r1​</span></span>​</span><span>(cos(<span><span>θ2</span>−<span>θ1​) </span></span>+ i sin(<span><span>θ2​</span>−θ1)</span><span>)
</span></span></span>

z1/z2

= 3/7 (cos(π/8-π/9) + i sin(π/8 - π/9))

= 3/7 (cos(π/72) + i sin(π/72))
