[tex] r = a sqrt{ cos(2 alpha ) } : diff : w : r : t : alpha [/tex]
Added by Timothy W.
Step 1
First, we need to take the derivative of the given equation with respect to alpha. [tex]\frac{dr}{d\alpha} = \frac{a}{2\sqrt{cos(2\alpha)}}(-sin(2\alpha))[/tex] Show more…

$r=f(\theta)$ vs. $r=2 f(\theta) \quad$ Can anything be said about the relative lengths of the curves $r=f(\theta), \alpha \leq \theta \leq \beta,$ and $r=2 f(\theta)$ $\alpha \leq \theta \leq \beta ?$ Give reasons for your answer.
