Webwhere R represents the radius of the helix, h represents the height (distance between two consecutive turns), and the helix completes N turns. Let’s derive a formula for the arc length of this helix using Equation 3.12. First of all, r ′ (t) = − 2πNR h sin(2πNt h)i + 2πNR h cos(2πNt h)j + k. Therefore, Webtake the reciprocal of i/di di=30 cm (it is positive) now we take salman's formula 1/f= 1/di +1/do (remember we are not taking sign conventions we are simply putting the values) 1/10= 1/di +1/15 (not applying sign convention) 1/di=1/10 -1/15 =1/30 we take the reciprocal of 1/di and di = 30 cm thus both the formulas are correct ! :) ( 24 votes)
