Topic: \(Calculus \ 2\), polar conversions
Q: Identify name & Cartesian equation for: r = 2\(\tan \theta \sec \theta\)
Any graphing calculator can quickly show this is a parabola the one I've sketched below, but I'm trying to understand the process here. These are the facts I know of:
\(r=\sqrt{x^2+y^2}\)
\(\theta = \tan^{1}(\frac{y}{x})\)
x = r cos θ
y = r sin θ
What's the trick here? Can somebody show me? (I'd be more than happy to give out a medal if you can do so) There are a few other problems related to this one I'm working on so a technique to be learned is the goa
