# Rectangular to Cylindrical (Equation)

MVCALC-LXRQSJ

Let $S$ be a surface given by the rectangular equation $y=4x^2$.

What is the cylindrical equation of $S$?

A

$4r^2=\tan \theta \cdot \sec \theta$

B

$4r=\tan \theta \cdot \csc \theta$

C

$4r=\tan \theta \cdot \sec \theta$

D

$4r=cot \theta \cdot \sec \theta$

E

$4r=\cot \theta \cdot \cos \theta$
