Question

Transform the rectangular equation x2=$$31yx^2=31y $$into a polar equation expressing rr in terms of θθ.

Accepted Answer

r=31sin⁡θcos⁡2θr=\frac{31\sin	heta}{\$$cos^2$$	heta}

Answer

r=31cos⁡2θr=\frac{31}{\$$cos^2$$	heta}

Answer

r=31cos⁡θsin⁡2θr=\frac{31\cos	heta}{\$$sin^2$$	heta}

Answer

r=31sin⁡θcos⁡θr=\frac{31\sin	heta}{\cos	heta}

Transform the rectangular equation x2=31yx^2=31y into a polar equation expressing rr in terms of θθ.
