a) \(ds = \int_a^b xy \sqrt{1 + (\frac{dy}{dx})^2} \)
b) \(ds = \int_a^b \sqrt{1 – (\frac{dy}{dx})^2} \,dx \)
c) \(ds = \int_a^b \sqrt{(\frac{dy}{dx})^2} \,dx \)
d) \(ds = \int_a^b \sqrt{1 – (\frac{dy}{dx})^2} \,dx \)
b) \(ds = \int_a^b \sqrt{1 – (\frac{dy}{dx})^2} \,dx \)
c) \(ds = \int_a^b \sqrt{(\frac{dy}{dx})^2} \,dx \)
