WebLength of curves. The basic point here is a formula obtained by using the ideas of calculus: the length of the graph of y = f ( x) from x = a to x = b is. arc length = ∫ a b 1 + ( d y d x) 2 d x. Or, if the curve is parametrized in the form. x = f ( t) y = g ( t) with the parameter t going from a to b, then. arc length = ∫ a b ( d x d t) 2 ... WebWe replace this in the other equation. x = 1 − t 2. x = 1 − ( y + 2) 2. x − 1 = − ( y + 2) 2. 1 − x = ( y + 2) 2. NOTE: Although one might solve for y, it is not necessary to do so, since the expression 1 − x will have to be taken as ± 1 − x. Thus, it is better to stick to the above parabola in " ( y, x) " rather than to a ...
