A Nice Arclength Problem Youtube Solution. determine the length of x = 4(3 y)2 x = 4 (3 y) 2 , 1 ≤ y ≤ 4 1 ≤ y ≤ 4. solution. here is a set of practice problems to accompany the arc length section of the applications of integrals chapter of the notes for paul dawkins calculus ii course at lamar university. Thinking of the arc length formula as a single integral with different ways to define \(ds\) will be convenient when we run across arc lengths in future sections. also, this \(ds\) notation will be a nice notation for the next section as well. now that we’ve derived the arc length formula let’s work some examples. 4.2: arc length. in section 4.1 we saw that one revolution has a radian measure of 2π rad. note that 2π is the ratio of the circumference (i.e. total arc length) c of a circle to its radius r: radian measure of 1 revolution = 2π = 2πr r = c r = total arc length radius. clearly, that ratio is independent of r. Likewise, the length of any arc is just the product of the measure of its spanning angle in radians and the radius of the circle. figure 4.2.7. so, for instance, we can use the formula to find the arc length spanned by an angle of 2.5 radians on a circle of radius six inches: s = rθ = (6inches)(2.5) = 15 inches.
