Question
Find the slope of the tangent line to the polar curve for the given value of $\theta$$$r=a \sec 2 \theta ; \quad \theta=\pi / 6$$
Step 1
The derivative of a polar curve is given by the formula: $$ \frac{dy}{dx} = \frac{dr}{d\theta} \sin(\theta) + r \cos(\theta) $$ where $r = a \sec(2\theta)$. Show more…
