Here's an idea:
import math
def sin_integral(start, finish, dx):
total = 0.0
y0 = math.sin(start)
for n in range(1, 1 + int((finish - start) / float(dx))):
y1 = math.sin(start + n * dx)
total += (y0 + y1)
y0 = y1
return total / 2. * dx
def cos_integral(start, finish, dx):
total = 0.0
y0 = math.sin(start)
for n in range(1, 1 + int((finish - start) / float(dx))):
y1 = math.cos(start + n * dx)
total += (y0 + y1)
y0 = y1
return total / 2. * dx
generalize and separate the integration technique from the
function it integrates.
