Then, that expression is plugged into the arc length formula. \[y\sqrt{1+\left(\dfrac{x_i}{y}\right)^2}. Let \( f(x)=\sin x\). Notice that we are revolving the curve around the \( y\)-axis, and the interval is in terms of \( y\), so we want to rewrite the function as a function of \( y\). However, for calculating arc length we have a more stringent requirement for \( f(x)\). Before we look at why this might be important let's work a quick example.
