Step 1 :Suppose an arc of length \(s\) lies on the unit circle \(x^{2}+y^{2}=1\), starting at the point \((1,0)\) and terminating at the point \((x, y)\).
Step 2 :Given that \(s=0.3\), we can use the hint given in the question that tells us that the x-coordinate of this point is \(\cos(s)\) and the y-coordinate is \(\sin(s)\).
Step 3 :Calculate \(\cos(0.3)\) and \(\sin(0.3)\) to find the coordinates of the point.
Step 4 :\(x = \cos(0.3) = 0.955336489125606\)
Step 5 :\(y = \sin(0.3) = 0.29552020666133955\)
Step 6 :Round the values of x and y to four decimal places.
Step 7 :\(x = 0.9553\)
Step 8 :\(y = 0.2955\)
Step 9 :\(\boxed{(x, y) = (0.9553, 0.2955)}\)
