Verify using polar form that $i^{9}$ $i^9$ is $i$ $i$ Can someone please help me with this? I tried doing this and came up with z=r= $\sqrt{1}$ $sqrt1$ (cos90 + $i$ $i$ sin90) And $z^{9}$ $z^9$ = $\sqrt{1}$ $sqrt1$ ^9(cos 810 + $i$ $i$ sin 810)
Please help How do you graph the polar equation r=8-sec $θ$ $theta$ ?
Please help How do I graph the polar equation $r^2=4sinθ$ ?
How do you find points to graph a polar equation? Say $r^2=4sintheta$
