## $L=\int_{0}^{\pi / 2} \sqrt{1+(1-\sin x)^{2}} d x \approx 1.7294$

he has clear suing you. Read here. So we hover formula Our equation minutes Why is equal to X was co sign and X is between zero and pi halves included. So we're going to graft first. It looks something like this on our derivative. We get a CZ one minus sign when we plug it into our length mark going Formula goes from zero to pie halves square root of one plus one minus sign squared d x When we calculated on the calculator they get around 1.7294 #### Topics
