Arc Length of Curves Calculus
The length of the segment connecting x→ (ti−1) and x→ (ti) can be computed as ‖x→ (ti)− x→ (ti−1)‖, so we have that the length of the curve is. L = ∫ − 2 2 1 + ( 2 ⋅ x) 2 d x 4.) √1 +( dy dx)2 = √( 5x4 6)2 + 1 2 +( 3 10x4)2. The opposite side is the side opposite to the angle of interest, in this case side a.; The length of a curve represented by a function, y = f ( x) can be found by differentiating the curve into a large number of parts. Integrate as usual, we want to let the slice width become arbitrarily small, and since we have sliced with respect to , we eventually want to integrate with respect to. These parts are so small that they are not a curve but a straight line. This means that the approximate total length of curve is simply a sum of all of these line segments: Recall that we can write the vector function into the parametric form, x = f (t) y = g(t) z = h(t) x = f ( t) y = g ( t) z = h ( t) also, recall that with two dimensional parametric curves the arc length is given by, l = ∫ b a √[f ′(t)]2 +[g′(t)]2dt l = ∫ a b [ f ′ ( t)] 2 + [ g ′ ( t)] 2 d t. We zoom in near the center of the segment oa and we see the curve is almost straight.
The opposite side is the side opposite to the angle of interest, in this case side a.; D y d x = 2 ⋅ x 3.) plug lower x limit a, upper x limit b, and d y d x into the arc length formula: L = ∫ a b 1 + ( f ′ ( x)) 2 d x. While finding the length of a curve, we assume an infinitesimal right triangle, of width d x and height d y, so arc length is d x 2 + d y 2. We can find the arc length to be 1261 240 by the integral. L = ∫ 2 1 √1 + ( dy dx)2 dx. L(x→) ≈ ∑ i=1n ‖x→ (ti)− x→ (ti−1)‖ = ∑ i=1n ‖ x→ (ti)− x→ (ti−1) δt ‖δt, where we both multiply and divide by δt, the length of each subinterval.

We zoom in near the center of the segment oa and we see the curve is almost straight. The hypotenuse is the side opposite the right angle, in.
