Calculating Length of Curves

Calculates the length of y=2x^2 over the range x=5mm to x=10mm using calculus.


import sympy
from sympy import *
 
x = Symbol('x')
 
formula = 2 * x**2
x_minimum = 5.0
x_maximum = 10.0
 
d = diff(formula, x)
i = integrate(sqrt(1 + d**2), (x, x_minimum, x_maximum))
length = i.evalf()
print 'Length of curve over x=%.3f to x=%.3f is %.3f mm' % (x_minimum, x_maximum, length)
