An illustration of the letter 'A' in a speech bubbles

Arc length of a curve C described by the parametric equations x=f(t) and y=g(t), `a<=t<=b` where f' and g' are continuous on [a,b] and C is traversed exactly once as t increases from a to b, then the length of the curve is given by,


We are given:`x=arcsin(t),y=ln(sqrt(1-t^2)), 0<=t<=1/2`







Now let's evaluate arc length by using the stated formula,







Using partial fractions integrand can be written as :


Take the constant out and use the standard integral:`int1/xdx=ln|x|+C`








Arc length of the curve on the given interval is `~~0.549`
