def dx(fn, x, delta=0.001):
return (fn(x+delta) - fn(x))/delta
def solve(fn, value, x=0.5, maxtries=1000, maxerr=0.00001):
for tries in xrange(maxtries):
err = fn(x) - value
if abs(err) < maxerr:
return x
slope = dx(fn, x)
x -= err/slope
raise ValueError('no solution found')
Answer:
<u>COPA full form or meaning is Computer Operator and Programming Assistant.</u>
A source is where you can look to find info. Multiple means many or some.
Therefore, a multiple source test is a test that you can find the answers in multiple sources, such as a book, article, journal, etc.
