Question
Find the slope of the line tangent to the following polar curves at the given points.$$r^{2}=4 \cos 2 \theta ;\left(0, \pm \frac{\pi}{4}\right)$$
Step 1
Step 1: The equation for the slope of the tangent line in polar coordinates is given by $\frac{dy}{dx} = \frac{dr/d\theta \cdot \sin\theta + r\cos\theta}{dr/d\theta \cdot \cos\theta - r\sin\theta}$. Show more…
