Question
Find the exact length of the polar curve.$ r = 2\cos\theta $, $ \quad 0 \leqslant \theta \leqslant \pi $
Step 1
Step 1: The formula for the length of a polar curve is given by \[ L = \int_{a}^{b} \sqrt{r^2 + \left(\frac{dr}{d\theta}\right)^2} d\theta \] where \( r = f(\theta) \) is the polar equation of the curve. Show more…
